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 3%
For brine-pickling: calculate 3% of total brine weight, not of vegetable weight. E.g., 1kg water = 30g salt. For dry-salting: less common at this %, but used for onions + harder root vegetables.
Safety: Safe range for lacto-fermentation. 2% is the most common default for cabbage, kimchi and pepper mash.
