Salt calculator
Enter your vegetable weight and a salt percentage. We return the exact salt mass in grams, plus teaspoons for each common grain.
Grain matters: one teaspoon of Diamond Crystal weighs half as much as one teaspoon of fine sea salt. Weigh in grams when you can.

About Swiss Chard
Best fermented in two parts: the crisp stems pickle like a mild celery, while the leaves ferment like a tender green. High water content makes the leaves wilt quickly, so they are often packed with the chopped stems for structure. A good way to preserve a glut of chard.

Technique
Separate leaves from stems. Cut stems into 1cm pieces and chop the leaves. Salt the combined weight at 2.5% and massage briefly, or brine the stems at 2.5% (25g salt per liter) and add the wilted leaves. Pack below the brine and ferment 7-14 days at 65-72°F; the stems stay crunch-forward.
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.
