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

Technique

Slice thin (3mm) or use whole pearl onions. Cover with 3% brine + 1 bay leaf + 1 tsp coriander seeds per pint. 10-14 days. For mixed ferments, add at 20% of primary vegetable weight.

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.
