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.

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.
