Japanese Ankake Sauce Thickened Starch Applications · The Japanese Canon

I

Origin

Japan — ankake thickening technique likely from Chinese influence, Nara period; naturalised into Japanese cuisine Heian period; current applications in kaiseki and home cooking throughout

Description

Ankake (あんかけ — 'poured-over sauce') is a category of Japanese thickened sauce applied to many preparations — from agedashi tofu to chilled tofu, from soft-boiled egg dishes to stir-fried vegetables. The technique involves thickening a dashi-based sauce with katakuriko (potato starch) or cornstarch to create a glossy, flowing sauce that coats ingredients and retains heat longer than a thin broth. Ankake appears across Japanese cuisine: in itamemono (stir-fried dishes), in nimono where the final sauce is thickened, as a sauce for steamed egg custard (chawanmushi ankake), and in Chinese-influenced Japanese dishes where the thick, glossy texture is a characteristic feature. The ratio for a standard ankake: dashi 200ml, light soy sauce 1 tablespoon, mirin 1 tablespoon, sake 1 tablespoon, katakuriko 2 teaspoons mixed with 2 teaspoons cold water (always cold — to prevent premature gelatinisation). The starch mixture is added to the simmering sauce in a slow, continuous pour while stirring constantly — a sudden dump creates lumps. The sauce thickens almost immediately at simmering temperature; it must not be overcooked or the starch breaks down and the sauce thins again. Ankake is used in cold-weather preparations to keep food warm longer at the table.

The Thread

—Japanese ankake and Chinese gōu qiàn are virtually identical techniques — both use starch-water slurry added to hot sauces; the technique likely arrived in Japan via Chinese cooking influence Chinese

—Both French arrowroot sauce and Japanese katakuriko ankake use non-wheat starch for clear, glossy sauce thickening — identical technique, different cultural contexts French

—Both Korean and Japanese cuisines use potato starch as the preferred thickener for clear, delicate sauces — reflecting the shared preference for potato starch over wheat flour in East Asian sauce-making Korean

Flavour Context

The sauce itself takes its flavour from the dashi base — ankake provides texture (glossy, flowing, heat-retaining) and visual appeal (glossy coat) rather than a distinct flavour of its own
