Technique
For kkakdugi: peel, cube 1.5cm, salt 3%, rest 30 min to draw water, drain, toss with kimchi paste. Ferment 5-7 days at room temp then fridge. For half-brine style: cube, cover with 4% brine, 7-10 days.
3.00% by weight is the default for daikon radish (workable range 2.50%–4.00%). For 1000g daikon radish, that's 30.0g salt. Use non-iodised salt and weigh in grams — teaspoon equivalences vary by salt grain. Source: Maangchi — kkakdugi recipe.
How long to ferment daikon radish?
10.0 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.
