Why You Should Learn to Ferment Something (Start with Kimchi)
2024-12-23 · 5 min read
Fermentation is one of the oldest food preservation techniques on the planet, and it requires almost no skill, no special equipment, and very little attention. You are essentially letting beneficial bacteria do the work while you do nothing. It is the most rewarding form of laziness available to a home cook, and the results are genuinely transformative.
Start with kimchi because the barrier to entry is absurdly low. You need napa cabbage, Korean chili flakes (gochugaru), fish sauce, garlic, ginger, sugar, and salt. Cut the cabbage, salt it for two hours, rinse it, mix it with a paste made from the other ingredients, pack it into a jar, and wait. That is it. Maangchi, the Korean cooking authority on YouTube, has a recipe that has been viewed over twenty million times for good reason.
The fermentation happens at room temperature over one to five days, depending on how funky you want it. You will see bubbles forming in the jar as the lactobacillus bacteria convert sugars into lactic acid. This is the same process that gives sourdough its tang and yogurt its bite. When it tastes right to you, move it to the fridge where it will continue to develop slowly for months.
Once you nail kimchi, the door opens to everything else. Sauerkraut is just cabbage and salt. Fermented hot sauce follows the same basic logic. Kombucha requires a SCOBY and some patience. Each project teaches you something about how bacteria and time transform raw ingredients into something more complex and nutritious.
The gut health benefits are real and well-documented. Fermented foods introduce beneficial probiotics to your digestive system, and studies published in journals like Cell have linked regular consumption of fermented foods to reduced inflammation markers. But honestly, you should do it because homemade kimchi tastes infinitely better than anything in a jar at the store.
