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 Kale
A sturdy brassica leaf that ferments into a robust, earthy kraut. Tougher and lower-water than cabbage, kale is usually destemmed and blended with shredded cabbage or salted firmly on its own. The thick leaves keep good texture and don't collapse the way tender greens do.

Technique
Strip leaves from the stems and chop or chiffonade. Salt at 2.5% of leaf weight and massage 5-8 minutes until wilted and weeping — the lower water content needs more massaging than cabbage. Pack tightly below the brine and ferment 7-18 days at 65-72°F. Blends well 50/50 with green cabbage.
Salt level notes at 2.5%
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.
Safety: Safe range for lacto-fermentation. 2% is the most common default for cabbage, kimchi and pepper mash.
