How to Ferment Vegetables at Home: Kimchi & Sauerkraut

This article was originally published on Sikho.ai. Read the full guide there.

Store-bought fermented vegetables cost $8-12 per jar, but you can make a month's supply at home for under five dollars. Fermentation is also one of the oldest, healthiest, and easiest food preservation methods on Earth.

In our full guide on Sikho.ai, we walk through the complete process. Here is the short version.

Why Ferment

Fermented vegetables contain beneficial probiotics that strengthen the gut biome. Health benefits include better digestion, reduced inflammation, immune support, and improvements to chronic conditions like IBS. Plus the flavor — there is nothing like homemade kimchi or sauerkraut.

The Basic Method

Salt + cabbage + time = sauerkraut. The ratio that works is 2% salt by weight of vegetables. Massage cabbage with salt for 5-10 minutes until liquid releases. Pack tightly into a jar so the brine covers everything. Keep at room temperature 1-3 weeks. Done.

For kimchi, the same principle but with napa cabbage, daikon, garlic, ginger, and Korean chili flakes. Same timing.

Common Mistakes

Wrong salt (table salt with iodine inhibits bacteria — use kosher or sea salt). Vegetables not submerged (must be under brine). Inconsistent temperature. Sealing too early (release CO2 daily for first week).
