Overview
Fermentation uses beneficial microbes to preserve and transform food. Vegetable ferments like sauerkraut and kimchi require little more than salt, vegetables, and a jar.
It is inexpensive, forgiving once you understand the basic safety rules, and it produces flavors you cannot buy.
Getting Started
Start with sauerkraut. Cabbage, salt, and a jar is the entire ingredient list.
Weigh your salt as a percentage of vegetable weight. This is what keeps ferments safe.
Keep vegetables submerged below the brine. Exposure to air is what causes mold.
Learn what normal looks and smells like versus spoilage — cloudy brine and sour smell are usually fine.
