Lacto-fermenting parsnip: 3.00% salt, 14.0days at 68 °F
A sweet, starchy winter root whose high sugar content fuels a vigorous, slightly effervescent ferment. The sweetness mellows into a complex, gently tangy pickle. Lower water content (~80%) means a brine-pickle works better than dry-salting.

Grain matters: one teaspoon of Diamond Crystal weighs half as much as one teaspoon of fine sea salt. Weigh in grams when you can.

Technique
Peel and cut into batons or 1cm coins. Cover with a 3% salt brine (30g salt per liter) plus optional bay, peppercorn, or ginger. Because parsnip is sugary, watch for active bubbling and burp the jar; ferment 10-18 days at 62-70°F, then refrigerate. Pairs well in a mixed root ferment with carrot and turnip.
3.00% by weight is the default for parsnip (workable range 2.50%–3.50%). For 1000g parsnip, that's 30.0g salt. Use non-iodised salt and weigh in grams — teaspoon equivalences vary by salt grain. Source: NCHFP (UGA) — fermented brine-pickle method.
How long to ferment parsnip?
14.0 days at 68°F (20°C). Cooler kitchens (60-65°F) slow fermentation; warmer kitchens (75-80°F) roughly halve the time per 10°F increase. Start tasting from day 5; target pH 3.80 or below indicates complete primary fermentation.
