Safety and use at 2.5%

The optimal salt level for lacto-fermenting hot peppers. Capsaicin doesn't affect Lactobacillus, but pepper flesh is lower-water than cabbage, so slightly higher salt % provides safety margin against the less-forgiving medium.

Technique notes

Standard for hot sauce base. Weighed at 2.5% of total pepper weight before any added brine. If adding aromatics (garlic, onion, carrot), those also count in the weight — 2.5% of combined total.
