Lacto-fermenting rutabaga: 2.50% salt, 14.0days at 68 °F
A dense brassica root (swede) that ferments slowly into a firm, mildly sweet pickle. Lower water content than turnip means it benefits from being cut small or grated and salted directly to draw brine. Holds its texture well over long ferments and keeps for months.

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 1cm cubes or coarse-grate. For cubes, brine at 2.5% (25g salt per liter); for grated, dry-salt at 2.5% of weight and massage until liquid pools, then pack below the brine. Ferment 10-21 days at 60-68°F. The slower, cooler ferment develops a rounder flavor.
2.50% by weight is the default for rutabaga (workable range 2.00%–3.50%). For 1000g rutabaga, that's 25.0g 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 rutabaga?
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.
