Lacto-fermenting green cabbage: 2.00% salt, 14.0days at 68 °F
The canonical lacto-ferment vegetable. Green cabbage is the backbone of traditional sauerkraut across German, Polish, and Russian cuisine. High water content (~92%) means it self-brines when salted and weighted — no added water required. Produces abundant Lactobacillus after 3-5 days at room temperature.
