This is an educational graphic novel about Sandor Ellix Katz, born 1962, the American fermentation revivalist and author who sparked the modern fermentation movement in the United States. Set primarily in Tennessee and New York from 1993 onward. The art style is contemporary folk art meets scientific illustration — warm earthy tones of crocks and clay, fermenting greens and golds, hand-drawn expressive style evoking craft and community, with microscopic bacterial worlds rendered as vibrant, friendly cartoon ecosystems. Sandor appears as a warm, exuberant, deeply enthusiastic man with curly dark hair, a beard, and colorful clothing — always surrounded by fermenting vessels and community. His character design remains consistent: curly hair, beard, bandana or colorful scarf, earth-toned clothing, joyful expression. The tone throughout is life-affirming and communal — fermentation here is not just food preservation but connection: to ancient traditions, to living microbes, to human community, and to personal health.Prologue – The Living Kitchen¶
For most of human history, every kitchen was a fermentation laboratory. Sauerkraut and kimchi preserved vegetables through winter. Miso and soy sauce transformed beans into profound flavors. Yogurt and cheese preserved milk for months. Sourdough and beer relied on wild microbes invisible to the naked eye. Then industrial food processing arrived and replaced these living foods with shelf-stable substitutes — and a generation grew up without ever making anything fermented. Sandor Katz changed that. Starting from a Tennessee farmhouse in 1993, he sparked a revolution that put crocks and cabbage back in millions of kitchens, and put microbiology into the hands of home cooks.
Panel 1: A Diagnosis and a Decision¶
Image Prompt
(This is Panel 1 of 12. Do not include the panel number in the image.) Wide 16:9 folk art graphic novel panel in warm, grounded tones. A doctor's office in New York City, 1991. Sandor Katz, age 29, with curly dark hair, a beard, and a worried expression, sits across from a physician in a clinical white office. The doctor holds a manila folder with test results. On the desk: a small framed photo, a box of tissues. Through the window: the gray winter city. Sandor's hands grip the edge of the chair. The moment depicted is the aftermath of receiving an HIV-positive diagnosis — Sandor's face shows a complex mixture of fear and a kind of resolving calm. In the corner of the panel: a small folk-art illustration of a fork in a road, one path leading to a gray cityscape, one leading to green hills — rendered in simple, hand-drawn style. Color palette: clinical white and gray for the office, with warm amber from a desk lamp suggesting a path forward. Visible details: the doctor's concerned but kind expression, health pamphlets on the counter, Sandor's colorful scarf against the clinical setting, a calendar showing the month, snow visible through the window. Emotional tone: the pivot moment, serious and real but not without hope. Generate the image immediately without asking clarifying questions.In 1991, Sandor Katz received a diagnosis that changed his life: he was HIV-positive. At the time, HIV was still a death sentence for most — effective antiretroviral treatments were years away — and the diagnosis forced Katz to confront fundamental questions about how he wanted to live. He had been working in New York City politics and activism, living a hectic urban life, and something about the diagnosis clarified what mattered. He decided to move to Short Mountain Sanctuary, an intentional community in rural Tennessee, to live more simply, grow food, and connect more deeply with the land. It was a choice that would lead him to fermentation — and eventually change food culture across America.
Panel 2: Arriving at the Farm¶
Image Prompt
(This is Panel 2 of 12. Do not include the panel number in the image.) Wide 16:9 folk art graphic novel panel in warm Tennessee autumn colors. Short Mountain Sanctuary, Tennessee, 1993. Sandor Katz, now 31, stands in a large organic vegetable garden in late fall, surrounded by the abundance of harvest — rows of enormous cabbages, kohlrabi, kale, beets, turnips stretching to the treeline. He is dressed in earthy work clothes, a colorful bandana around his neck, work gloves in one hand, looking with curiosity at the massive pile of harvested vegetables around him. Other community members work in the background — diverse people in garden clothing, laughing and working together. The landscape is rolling Tennessee hills with autumn colors, a weathered farmhouse visible in the background. Color palette: rich harvest amber, deep vegetable green, Tennessee red clay soil, warm autumn sky. Visible details: dew on the cabbages, mud on work boots, the sheer abundance of more vegetables than anyone could eat fresh, a wooden barn in the background, a community garden sign hand-painted and weathered. Emotional tone: the sensory richness of abundance, the satisfying weight of harvest, a new beginning. Generate the image immediately without asking clarifying questions.Katz arrived at Short Mountain in 1993 to find himself surrounded by the Tennessee landscape's extraordinary abundance — and the community's very practical problem of what to do with more vegetables than anyone could eat fresh. Living with a farming community meant confronting an ancient human puzzle: how do you preserve the harvest of summer to eat through winter? The freezer could handle some of it, but the electricity was unreliable and the community prided itself on low-tech solutions. A community elder showed Katz a ceramic crock, a head of cabbage, and a bag of salt — and introduced him to the 2,000-year-old technology of lacto-fermentation. Katz's life would never be the same.
Panel 3: The Crock of Sauerkraut¶
Image Prompt
(This is Panel 3 of 12. Do not include the panel number in the image.) Wide 16:9 folk art graphic novel panel with warm kitchen light. A farmhouse kitchen, Tennessee, 1993. Sandor Katz stands at a rough wooden kitchen table with an elder woman beside him — gray-haired, experienced hands moving with confidence — showing him how to make sauerkraut. On the table: a large ceramic crock, a head of green cabbage being shredded by hand, a bowl of coarse sea salt, a wooden tamper. The elder's hands guide Sandor's as he packs the salted cabbage into the crock, pressing out brine. A floating folk-art scientific illustration shows the process in simple icons: cabbage + salt → brine → Lactobacillus bacteria (shown as friendly round pink characters) → lactic acid → preserved sauerkraut. Color palette: warm farmhouse amber and cream, the bright fresh green of cabbage before fermentation, rich clay red of the crock. Visible details: the brine beginning to rise above the packed cabbage, salt crystals visible on the shredded cabbage, the elder's worn apron, a window showing the Tennessee farm outside, other crocks along the wall at different stages of fermentation. Emotional tone: transmission of ancient knowledge, the intimacy of teaching through hands. Generate the image immediately without asking clarifying questions.Katz's introduction to fermentation came through sauerkraut — one of the simplest and most ancient fermented foods in human culture. The recipe requires only two ingredients: cabbage and salt. The salt draws water out of the cabbage cells through osmosis, creating a brine. Submerged in that brine, cut off from oxygen, the naturally occurring Lactobacillus bacteria on the cabbage leaves begin to thrive — they don't need to be added, they are already there. These bacteria produce lactic acid as they consume the cabbage sugars, and that lactic acid preserves the vegetables, prevents harmful bacteria from growing, and creates the pleasantly sour flavor that makes sauerkraut what it is. Katz tasted his first homemade sauerkraut and understood, on a gut level, that this was something important.
Panel 4: A World of Fermented Foods¶
Image Prompt
(This is Panel 4 of 12. Do not include the panel number in the image.) Wide 16:9 folk art graphic novel panel showing a world food map of fermentation. Sandor Katz sits in a farmhouse with a large world map spread on the table, surrounded by books about food culture from Korea, Germany, Japan, Ethiopia, Scandinavia. His face is lit with excitement as he traces his finger across the map. Around the map's edges, folk-art illustrations show fermented foods from each region: kimchi from Korea (bright red, illustrated with Korean characters), miso from Japan (deep amber paste in wooden tubs), injera from Ethiopia (spongy flat bread on a clay griddle), kvass from Russia (dark bread beer in wooden barrels), yogurt from Turkey (white and thick in clay bowls). Each regional illustration connects to the map with a hand-drawn line. Color palette: warm map amber and cream at center, bright folk-art colors for each regional vignette, the earthy browns of the farmhouse table. Visible details: Post-it notes and handwritten marginalia in Sandor's books, a half-eaten piece of sourdough bread on the table, a mason jar of fermenting vegetables nearby, the afternoon light on the map. Emotional tone: the joy of discovery, the realization that a practice spans all of human civilization. Generate the image immediately without asking clarifying questions.As Katz learned sauerkraut, he began researching the full scope of what he had stumbled into — and discovered that fermented foods are not a quirky survivalist technique but the foundation of food cultures around the entire globe. In Korea, kimchi (fermented spiced cabbage and vegetables) has been made for over 2,000 years and remains a dietary staple. Japan's miso (fermented soybean paste) has a thousand-year history. Ethiopia's injera (fermented teff flatbread) is the foundation of every meal. Every culture, on every continent, independently discovered that controlled microbial fermentation preserved food, created new flavors, and — though they didn't know why — supported health. Katz realized he hadn't discovered a novelty. He had rediscovered something humans nearly forgot.
Panel 5: The Science of Lactic Acid Fermentation¶
Image Prompt
(This is Panel 5 of 12. Do not include the panel number in the image.) Wide 16:9 folk art meets scientific illustration panel. Split composition showing both the visible and microscopic world of a fermentation crock. Top half: a beautiful ceramic crock packed with shredded cabbage submerged in brine, viewed from slightly above and to the side, with a weighted lid holding the vegetables below the brine surface. Airlock bubbles escaping. Bottom half: a magnified cross-section of the crock brine rendered in vibrant folk-art scientific style — showing Lactobacillus bacteria as friendly round pink characters with flagella, moving through the brine, absorbing glucose molecules (shown as hexagonal yellow shapes) and expelling lactic acid molecules (shown as smaller three-carbon chains in orange). The pH scale runs along the right side, dropping from 7 to 3.5 as fermentation progresses, shown with color gradient from blue (neutral) to orange (acidic). Color palette: earthy crock brown and cream above, bright folk-art pink, gold, and orange below. Visible details: the brine line clearly above the cabbage, bubbles rising, the decreasing pH color change shown on vegetables becoming more yellow-orange, harmful bacteria (shown as angular red shapes) visibly dying as pH drops. Emotional tone: the beauty of chemistry at work, microscopic life as vivid community. Generate the image immediately without asking clarifying questions.The science behind sauerkraut and kimchi is called lactic acid fermentation, and it is one of the most elegant systems in the microbial world. Lactobacillus bacteria — naturally present on raw vegetables, in soil, and in the air — are facultative anaerobes, meaning they prefer environments without oxygen. When vegetables are salted and packed tightly (removing oxygen), the Lactobacillus population explodes. These bacteria consume the simple sugars in the vegetables and produce lactic acid as a byproduct. As lactic acid accumulates, the pH drops from neutral (7) to around 3.5 — highly acidic — creating an environment where pathogenic (harmful) bacteria cannot survive. The Lactobacillus are, in effect, manufacturing their own preservative. It is a system that has kept food safe and flavorful for thousands of years, no refrigeration required.
Panel 6: Kimchi, Miso, and the Flavors of Fermentation¶
Image Prompt
(This is Panel 6 of 12. Do not include the panel number in the image.) Wide 16:9 folk art graphic novel panel showing Sandor Katz in his farmhouse kitchen engaged in a fermentation project, surrounded by the rich palette of fermented foods at different stages. On the table: a large clay crock of kimchi — bright red-orange from gochugaru pepper, with visible cabbage and daikon, a wooden spoon beside it; a wooden tub of pale miso paste; glass jars of brine-fermented vegetables in jewel tones — purple cabbage brine, golden turnip, deep green cucumber. Sandor is tasting a spoonful of kimchi with his eyes half-closed in sensory pleasure. Above the scene: folk-art flavor diagrams showing the layered complexity — sourness from lactic acid, umami from amino acids, heat from capsaicin, funk from complex fermentation esters — illustrated as stacked flavor layers like a geological cross-section. Color palette: vivid kimchi red-orange as the dominant tone, miso amber, brine jewel colors, warm farmhouse light. Visible details: Sandor's colorful bandana and work apron, handwritten labels on each jar with dates started, a notebook open to fermentation observations, a large window showing the Tennessee hills. Emotional tone: sensory abundance, the discovery of flavors built by microbes. Generate the image immediately without asking clarifying questions.The flavors of fermented foods go far beyond simple sourness — they represent the cumulative chemistry of microbial ecosystems working over days, weeks, or years. Kimchi develops its complex flavor from the interaction of Lactobacillus bacteria, gochugaru pepper compounds, garlic, ginger, and fish sauce in an anaerobic environment, producing not just lactic acid but hundreds of flavor esters and amino acid derivatives. Miso, made from soybeans fermented with Aspergillus oryzae mold and Lactobacillus bacteria for months or years, develops deep umami flavors from the breakdown of soy proteins into free amino acids. Each fermented food is a collaboration between specific microbial communities and specific raw ingredients — a fact that makes fermentation feel less like a recipe and more like ecology. Katz was becoming a student of entire living systems.
Panel 7: Writing Wild Fermentation¶
Image Prompt
(This is Panel 7 of 12. Do not include the panel number in the image.) Wide 16:9 folk art graphic novel panel showing the writing of a book in a farmhouse setting. A rustic Tennessee farmhouse writing space, 2001. Sandor Katz sits at a simple wooden desk with a laptop computer looking slightly out of place in the rustic setting — beside the laptop: crocks of fermenting vegetables, stacks of handwritten notes, printed photos of fermentation projects. He is writing intently, and the text on his laptop screen reads the first chapter of "Wild Fermentation." On the wall behind him: a hand-drawn map of fermentation types, folk-art illustrations he has made for the book, reader letters from early community workshops. Through the window: a summer garden, lush and green. Color palette: warm farmhouse cream and amber, the bright green of summer through the window, the hand-drawn folk-art quality of his illustrations in primary colors on the wall. Visible details: a glass of kombucha on the desk (SCOBY visible at top), a jar of sourdough starter bubbling beside the laptop, the earnest determination in his posture and expression, a handwritten outline pinned beside the screen. Emotional tone: the quiet power of putting important knowledge into a book, the feeling that this matters. Generate the image immediately without asking clarifying questions.By the late 1990s, Katz had been fermenting for years, teaching workshops at Short Mountain and at community events, and had accumulated enough knowledge and passion to write the book that would change everything. Published in 2003 by Chelsea Green Publishing, Wild Fermentation: The Flavor, Nutrition, and Craft of Live-Culture Foods was unlike any food book that had come before. It was practical enough to get a beginner fermenting on their first weekend, but deep enough in history, science, and philosophy to give that practice real meaning. Katz wrote it as an invitation — not to follow precise recipes but to engage with a living process. The book's radical message was that fermentation is not complicated, not dangerous, and not the exclusive domain of experts: it belongs to everyone.
Panel 8: The Workshops Begin¶
Image Prompt
(This is Panel 8 of 12. Do not include the panel number in the image.) Wide 16:9 folk art graphic novel panel showing a community fermentation workshop outdoors. A farmers market or community gathering, Tennessee, circa 2004. Sandor Katz stands at a long wooden table outdoors, sunlight filtering through trees, surrounded by 15-20 people of diverse ages and backgrounds — children, elderly people, young farmers, city visitors — all gathered around crocks and jars of fermenting foods. Sandor is demonstrating sauerkraut-making with great animated enthusiasm, hands pressing cabbage into a crock, his expression joyful and expansive. Participants lean in with curiosity, tasting from small cups, asking questions. On the table: cabbages being shredded, salt in a wooden bowl, an array of completed ferments in various vessels to examine. Floating folk-art bacteria characters dance above the demonstration, turning the science lesson into something playful. Color palette: dappled outdoor light, warm greens and earth tones, the bright folk-art bacteria in pink and gold as connecting visual thread. Visible details: Sandor's signature colorful bandana and enthusiastic gestures, a child tasting sauerkraut with a surprised-then-pleased expression, participants taking notes, jars labeled with different fermentation experiments. Emotional tone: the joy of sharing knowledge in community, the democratic accessibility of ancient craft. Generate the image immediately without asking clarifying questions.After Wild Fermentation was published, Katz began receiving invitations to teach fermentation workshops everywhere — farmers markets, homesteads, food conferences, universities, and community centers across North America and eventually the world. He accepted almost all of them, turning himself into a traveling fermentation evangelist. His workshops were not lectures: they were hands-on sessions where everyone got their hands into a crock of cabbage and salt. This democratic, participatory approach to food education was part of Katz's philosophy — fermentation knowledge should not be hoarded by experts but shared freely, and the best way to learn it was to do it. He was, as one food writer noted, the "Johnny Appleseed of American fermentation."
Panel 9: The Gut Microbiome — Ancient Wisdom, New Science¶
Image Prompt
(This is Panel 9 of 12. Do not include the panel number in the image.) Wide 16:9 folk art meets scientific illustration panel. Left side: Sandor Katz reading a thick scientific journal titled "Gut Microbiota and Human Health" at a farmhouse table, his expression showing the recognition of something he has known experientially now confirmed by science. Right side: a large folk-art illustration of the human digestive system — shown as a vibrant ecosystem, not a clinical diagram — with the intestines depicted as a lush living landscape populated by diverse Lactobacillus and Bifidobacterium characters in bright folk colors, hundreds of distinct species shown as unique characters building communities, interacting, competing, thriving. Labels point to key species: "Lactobacillus acidophilus," "Bifidobacterium longum," "Bacteroides." At the base of the illustration: fermented foods — sauerkraut, kimchi, yogurt, kefir — shown as supplies being delivered to the ecosystem. Color palette: warm farmhouse amber on the left, vibrant folk-art ecosystem colors (blues, greens, pinks, golds) on the right. Visible details: specific scientific citation dates (2000s microbiome studies), Sandor's finger on a key passage, the contrast between his informal setting and the formal scientific document. Emotional tone: validation, the convergence of ancient practice and modern discovery. Generate the image immediately without asking clarifying questions.As Katz was teaching his workshops based on intuition, tradition, and a sense that fermented foods felt life-giving, scientists in the early 2000s were beginning to map the human gut microbiome — the community of roughly 100 trillion microorganisms living in the human digestive tract. What they found validated what Katz had been saying intuitively: a diverse, healthy gut microbiome correlates strongly with overall health, immune function, mental health, and disease resistance. Fermented foods containing live bacteria — properly made sauerkraut, kimchi, yogurt, kefir, miso — deliver live Lactobacillus and other beneficial bacterial species directly to the gut, potentially supporting microbiome diversity. Ancient food traditions had been supporting human gut health for millennia without knowing the mechanism. The new science gave the ancient wisdom a molecular explanation.
Panel 10: The Kombucha in the Crock¶
Image Prompt
(This is Panel 10 of 12. Do not include the panel number in the image.) Wide 16:9 folk art graphic novel panel showing the expanding world of fermentation beyond vegetables. A farmhouse kitchen transformed into a fermentation laboratory — every available surface covered with different projects in different vessels: a large glass jar with kombucha brewing (the SCOBY — symbiotic culture of bacteria and yeast — shown as a thick pale disc floating at the top, with amber tea beneath); a ceramic crock of miso with a weight on top; a flip-top bottle of fizzy water kefir; a sourdough starter in a mason jar, actively bubbling; a bucket of beer in secondary fermentation with an airlock. Sandor moves through the space with delight, the conductor of this microbial symphony. Each vessel has a folk-art character bubble above it showing the specific microbial community inside — SCOBY shown as a cooperative community of bacteria and yeast, miso as a three-part community of mold, bacteria, and yeast working in layers. Color palette: the warm amber of kombucha and miso, the creamy white of kefir, the gray-green of sourdough, all in warm farmhouse light. Visible details: handwritten labels with start dates, the musical quality of each vessel's different bubbling rhythm, Sandor's satisfied expression surveying his diverse fermentation projects. Emotional tone: abundance, the sense of a living household full of intentional microbial partners. Generate the image immediately without asking clarifying questions.Katz's fermentation practice expanded far beyond sauerkraut into the full spectrum of fermented foods — kombucha, kefir, miso, tempeh, kvass, rejuvelac, fermented hot sauces, and dozens more. Each one taught him something new about the diversity of microbial partnerships that humans had cultivated over centuries. Kombucha, for instance, depends on a SCOBY — a Symbiotic Culture Of Bacteria and Yeast — a literally visible disc of microbial community that grows and can be shared with other brewers, passed person to person like a living gift. Katz began to see fermentation not as a technique but as a relationship: an ongoing collaboration between humans and the microbial world that had sustained human civilization for all of recorded history, and that modern industrial food processing had very nearly severed.
Panel 11: The Art of Fermentation — A Master Work¶
Image Prompt
(This is Panel 11 of 12. Do not include the panel number in the image.) Wide 16:9 folk art graphic novel panel showing a book launch and its worldwide impact. Left panel composition: Sandor Katz at a crowded bookstore reading, holding up his large new book *The Art of Fermentation* (2012), a thick volume with folk-art cover design. The audience is packed and diverse — serious food scientists in academic dress, home fermenters with mason jars on their laps, young food activists, restaurant chefs in whites. Right panel composition: a montage of the book's international reach — same book cover visible in Korean (Hangul), German, French, and Japanese editions spread on a table; below that, a collage of magazine covers featuring "fermentation revival" stories and photos of the fermentation movement it inspired; a small grocery store shelf showing the kombucha section, with over a dozen commercial brands filling the shelves. Color palette: vibrant folk-art energy throughout, warm amber lighting for the bookstore, clean commercial lighting for the grocery section. Visible details: a "Sold Out" sign on the shelf behind Sandor, people in the audience holding up worn copies of his first book alongside the new one, the sheer variety of fermentation vessels people brought to the event. Emotional tone: the arrival of a movement, the moment when underground becomes mainstream. Generate the image immediately without asking clarifying questions.In 2012, Katz published The Art of Fermentation — a massive, encyclopedic work that took the fermentation revival to its full scope. At 528 pages, it covered every major category of fermented food and drink across all human cultures, with detailed science, practical guidance, and cultural history for each. The book won the James Beard Foundation Award and immediately became the definitive reference on the subject. By this point, Katz's first book had already sparked a full cultural movement: kombucha had gone from a countercultural curiosity to a $1.8 billion industry; farmers markets across the country now included fermentation vendors; home fermentation supply companies had sprung up nationwide. The fermentation revival that Katz had begun in a Tennessee farmhouse had reached millions of people.
Panel 12: A Living Legacy¶
Image Prompt
(This is Panel 12 of 12. Do not include the panel number in the image.) Wide 16:9 folk art graphic novel panel showing the living legacy of the fermentation movement as a continuous human chain. A beautifully composed montage across time and space, folk-art style with vibrant warm colors. Far left: a Korean grandmother's hands packing kimchi into a clay onggi pot — traditional, ancestral. Center-left: Sandor Katz at a farmhouse table in the 2000s teaching a workshop, the same hands-in-cabbage gesture from before. Center: a young food science student at a university laboratory table examining fermented samples under a microscope, a copy of Katz's book beside the microscope. Center-right: a small-batch hot sauce producer at a farmers market, jars of fermented hot sauces labeled with folk-art designs. Far right: a teenager at a kitchen counter adding salt to shredded cabbage in a mason jar, following instructions on a phone, beginning their first ferment. Above all five figures: a continuous ribbon of folk-art Lactobacillus bacteria characters linking them across time — the same microbes, the same tradition, the same living gift. Color palette: warm earthy tones throughout, the bright pink of Lactobacillus characters as the unifying visual thread. Emotional tone: continuity, the living transmission of ancient knowledge, the joy of being part of something larger than yourself. Generate the image immediately without asking clarifying questions.Sandor Katz's legacy is ultimately about connection — between humans and microbes, between modern people and ancient traditions, between individual health and ecological health. Starting from a moment of personal crisis, facing a life-threatening illness with curiosity and openness, he found in fermentation something that sustained him physically and spiritually. He then spent three decades sharing that discovery with the world. The fermentation revival he sparked has changed how millions of people eat, has returned traditional food preservation to American kitchens, and has helped legitimate the science of the gut microbiome in mainstream culture. Perhaps most importantly, he demonstrated that ancient food wisdom and modern science are not in opposition — they tell the same story about the living world.
Epilogue – What Made Sandor Katz Different?¶
What distinguished Katz was not expertise inherited from formal training — he was self-taught, learning through practice and deep reading — but rather his extraordinary capacity for enthusiasm and his commitment to sharing knowledge freely. He could have monetized his knowledge through proprietary methods or exclusive teaching; instead, he wrote books designed to make himself unnecessary, books that gave readers everything they needed to teach themselves and each other. The fermentation movement he built is, appropriately, distributed and self-sustaining — exactly like a well-tended crock of sauerkraut.
| Challenge | How Katz Responded | Lesson for Today |
|---|---|---|
| Life-threatening illness with no cure | Used the situation to clarify values and deepen connection to life | Crisis can be a compass pointing toward what matters |
| Ancient knowledge nearly lost to industrialization | Learned it directly from practitioners and books, then shared it widely | Knowledge shared freely multiplies; knowledge hoarded disappears |
| Fermentation seen as dangerous or complicated | Demonstrated it is simple, safe, and universally accessible | Demystifying expertise gives power back to communities |
| Mainstream food culture dismissing traditional methods | Accumulated scientific evidence that validated traditional wisdom | Patience: sometimes the science catches up to the practice |
Call to Action¶
The next time you eat yogurt, sourdough bread, soy sauce, miso soup, or pickles — you are eating the work of billions of microbes. Fermented foods are not exotic or unusual: they are some of the oldest and most universal foods in human culture. Start with a simple sauerkraut: one head of cabbage, a tablespoon of salt, a jar, and patience. You will be doing exactly what humans have done for 2,000 years, and feeding trillions of your gut bacteria at the same time.
