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 Red Radish
Small red globe radishes ferment quickly and tint the brine a vivid pink. Their high water content and thin skins mean they sour in under a week, developing a mellow, slightly fizzy bite far gentler than raw radish. A common quick component in mixed-vegetable ferments and Korean-style banchan.

Technique
Trim and halve or quarter larger radishes; leave small ones whole. Pack into a jar and cover with a 2.5% salt brine (25g salt per liter). Weigh below the brine and ferment 3-7 days at 65-72°F — taste from day 3. Refrigerate once pleasantly sour to keep the snap.
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.
