Grain matters: one teaspoon of Diamond Crystal weighs half as much as one teaspoon of fine sea salt. Weigh in grams when you can.

Based on Fine sea salt at 5.69 g/tsp.

Flavour-forward. Ferment will be slower; brine will taste salty. Good for pickles and hot-sauce mashes that need long shelf life.

About Jalapeño Pepper

Workhorse for lacto-fermented hot sauce. Medium heat (2500-8000 SHU). Capsaicin is not water-soluble and doesn't inhibit Lactobacillus at dietary levels — fermentation proceeds normally regardless of pepper heat.

Technique

Remove stems (keep seeds for heat). Puree or chop coarse. Weigh, salt at 2.5%. Pack in jar, cover with brine if not self-brining. Ferment 7-14 days. Blend smooth with vinegar (to adjust to final pH 3.0-3.5), strain, bottle. Refrigerate 6+ months.

Salt level notes at 4%

Never use 4% for final dry-salted sauerkraut — way too salty. Only for pre-ferment rinse stages or for dilute brines (kvass) where the resulting beverage is drunk diluted or cooking vinegar.

Safety: Flavour-forward. Ferment will be slower; brine will taste salty. Good for pickles and hot-sauce mashes that need long shelf life.
