15 fermented foods that are easier to make than you think
Fermentation is one of the oldest food techniques in the world and one of the easiest to do at home — these 15 foods prove that the homemade version is almost always the best one

Fermentation has a reputation it does not entirely deserve. The word conjures images of laboratory equipment, precise temperature control, and the kind of specialist knowledge that takes years to acquire. The reality is considerably more accessible. Humans have been fermenting food since before recorded history — since long before anyone understood what fermentation was — using nothing more than salt, water, time, and the microorganisms that exist naturally on vegetables, in milk, and in the air. The technique is not a modern wellness trend. It is the oldest form of food preservation in the world, and it is substantially easier than most people who have not tried it assume.
What fermentation does, at the most basic level, is allow microorganisms — bacteria, yeasts, or molds — to transform the sugars and starches in a food into something else: acids, alcohols, gases, or new flavor compounds. The transformation preserves the food, in many cases improves its flavor significantly, and in others produces nutritional changes — increased bioavailability of certain nutrients, the development of beneficial bacterial cultures — that make fermented versions of foods meaningfully different from their raw equivalents. A fermented cabbage is not simply a preserved cabbage. It is a different food, with different flavors, different chemistry, and a different relationship to your digestive system.
The 15 fermented foods on this list were chosen for a specific combination of qualities: they are genuinely worth making, the homemade version is noticeably better than or different from what is available commercially, and the process is accessible enough that a first-time fermenter can succeed on the first attempt with standard kitchen equipment. None of them require specialist cultures that must be ordered online, though several are improved by them. None require temperature-controlled chambers, specialized crocks, or equipment beyond what most kitchens already contain.
Each slide covers what the food is, why it is worth making, and how to make it — with enough process detail to actually do it rather than simply understand it conceptually. The methods given are the simplest reliable versions of each preparation. Fermentation rewards curiosity and experimentation, and each of these foods has a universe of variation beyond the basic method — different vegetables, different salt levels, different fermentation times, different microbial cultures — that rewards continued exploration.
One note on safety: lacto-fermented vegetables, dairy ferments, and grain ferments are among the safest food preservation methods available. The acidic environment created by fermentation is inhospitable to the pathogens responsible for food poisoning. Trust your senses — a ferment that smells genuinely bad rather than pleasantly sour has failed and should be discarded — and the process is remarkably forgiving.
Sauerkraut is the entry point to fermentation for most beginners, and it earns that position by being almost impossible to fail at and by producing a result — tangy, complex, deeply savory fermented cabbage — that is so far superior to the pasteurized commercial product that the two barely merit comparison. The commercial version, heated to stop fermentation for shelf stability, has lost the living bacterial cultures and much of the nuanced flavor that make fresh sauerkraut worth eating. The homemade version, made with two ingredients and no equipment beyond a jar, is a different food entirely.
The method is the simplest in fermentation: salt and cabbage, massaged together until the cabbage releases enough liquid to submerge itself. Shred one medium head of white cabbage — about one kilogram — as finely as you can manage, discarding the outer leaves but reserving one large leaf. Weigh the shredded cabbage and add 2% of its weight in non-iodized salt — roughly two teaspoons per 500 grams. The iodized salt in standard table salt inhibits the bacteria responsible for fermentation; use sea salt, kosher salt, or pickling salt.
Massage the salt into the cabbage vigorously for five to ten minutes, squeezing and pressing until the cabbage has wilted significantly and released a substantial amount of liquid — brine that will submerge the cabbage during fermentation. Pack the cabbage tightly into a clean glass jar, pressing down firmly after each addition so the brine rises above the cabbage. Place the reserved cabbage leaf on top to hold the shreds below the brine. Leave at least five centimeters of headspace at the top — the ferment will bubble and expand.
Cover loosely — a cloth secured with a rubber band, or a lid left slightly ajar — and leave at room temperature, out of direct sunlight, for five to seven days. Check daily, pressing the cabbage down if it rises above the brine. Taste from day three onward — the sourness develops gradually, and when it tastes right to you, it is ready. Transfer to the refrigerator, where fermentation slows dramatically and the sauerkraut will keep for months.

Kimchi is to Korean cooking what sauerkraut is to central European cooking — not an accompaniment but a foundational element, present at almost every meal, made in such variety that entire books have been written on its variations. The most familiar version — baechu kimchi, made from napa cabbage — is the correct starting point for a home fermenter, and the process is more forgiving than its reputation suggests.
The key ingredients are napa cabbage, Korean chili flakes (gochugaru), fish sauce or salted shrimp paste, garlic, ginger, and green onions. The gochugaru — a coarsely ground, moderately spiced chili with a distinctive fruity flavor — cannot be substituted with standard chili flakes without significantly altering the result. It is available from Korean grocery stores and increasingly from well-stocked Asian supermarkets.
Quarter one large napa cabbage lengthwise and cut into rough pieces. Dissolve four tablespoons of salt in a liter of water and submerge the cabbage, weighting it down to keep it submerged, for two to four hours until the leaves have wilted and become pliable. Rinse thoroughly and squeeze out as much water as possible.
Make the paste: combine three tablespoons of gochugaru, four cloves of garlic grated or minced to a paste, a thumb of fresh ginger grated, two tablespoons of fish sauce, one tablespoon of sugar, and four sliced green onions. Wear gloves — the chili stains and irritates skin. Combine the paste with the cabbage, working it thoroughly into every layer. Pack into a clean jar, pressing down firmly to eliminate air pockets. Leave at room temperature for one to two days, pressing the kimchi down twice daily as it bubbles and expands. Transfer to the refrigerator — the kimchi is ready to eat immediately but improves significantly over the following two weeks as the flavors develop.
Yogurt is the most accessible dairy ferment and requires the least specialist knowledge to produce successfully. The method has been used in some form for at least 8,000 years across the Middle East, Central Asia, and South Asia, and it produces a result — thick, tangy, complex in flavor — that most commercial yogurts, stabilized........
