About Zucchini

A high-water summer squash that ferments fast but softens easily. Like cucumber, zucchini's ~95% water content makes it prone to going mushy, so it is brined at a higher salt percentage (3.5-5%) to keep the flesh firm and slow softening. Best fermented in spears or thick coins rather than shredded.

Technique

Cut into spears or 1cm coins. Submerge in a 3.5-5% salt brine (35-50g salt per liter of water) with a grape, oak, or horseradish leaf for tannins that preserve crunch; add garlic and dill if desired. Keep fully under the brine with a weight at 65-72°F for 5-10 days, then refrigerate once sour. Firmer at the lower end of the time range.

Salt level notes at 2%

Default. If in doubt, use 2.0%. The Noma Guide to Fermentation, NCHFP, Sandor Katz, and King Arthur all cite this as their baseline recommendation.

Safety: Safe range for lacto-fermentation. 2% is the most common default for cabbage, kimchi and pepper mash.
