TypeSalt-free lactic-fermented turnip greens

What is it?

Sunki-zuke ferments blanched Kiso turnip greens without any salt, using a portion of successful previous sunki or a prepared starter to seed lactic-acid bacteria. The result is clean, distinctly sour greens.

History and local context

Kiso's inland mountain setting made salt historically valuable, encouraging this unusual salt-free preservation method. Households maintained their own fermentation lineages, and the finished acidity became a defining winter taste.

How to enjoy it

Top chopped sunki with bonito and soy, add it to miso soup, or serve it in soba as sunki-soba. Because there is no protective salt, control temperature and acidity carefully; beginners should use a reliable starter or commercial product and discard failed batches.

Availability varies by maker, season, and destination.
