Shibazuke Kyoto Eggplant Purple Pickle Summer

Ohara, Kyoto Prefecture — attributed to 12th century origin; production unchanged for approximately 800 years

Shibazuke is one of Kyoto's three great pickles (sanzuke alongside suguki and senmaizuke) — a vibrant purple-red lacto-fermented preparation of eggplant (nasu) and cucumber combined with red perilla leaves (aka shiso) and salt, whose striking magenta color comes entirely from the natural anthocyanin pigments of the shiso reacting with the salt-induced acidity during fermentation. The pickle originated in Ohara, a mountain village northeast of Kyoto, traditionally attributed to the wife of Emperor Antoku who retreated there in the 12th century, and the recipe has remained essentially unchanged for over 800 years. The preparation involves slicing eggplant and cucumber into rounds or diagonal pieces, combining with torn shiso leaves and generous salt, then pressing under heavy weights for 2-3 days during summer heat (shibazuke is a summer pickle, ideally made July-August) while lactic acid fermentation begins naturally. The shiso contributes its characteristic herbal anise-adjacent aroma alongside the color transformation as anthocyanins interact with the acidic fermentation environment to produce the characteristic deep magenta. Traditional Ohara shibazuke uses only salt — no vinegar — distinguishing it from commercial versions that often add vinegar for consistent acidity and faster production.

Tangy-salty with herbal shiso anise note; eggplant provides soft textural contrast to firmer cucumber; the purple brine carries concentrated shiso-lactic flavor; distinctly different from vinegar pickles
