Ankake Thickened Sauce and Ankake Udon

Japan — technique present in ancient Chinese-influenced cooking; codified in Japanese culinary tradition; ankake udon particularly associated with Kyoto and Kansai winter cooking

Ankake refers to any dish finished with a thickened glossy sauce made from dashi or cooking liquid combined with katakuriko (potato starch) or kuzu starch slurry. The technique creates a coating sauce that clings to ingredients, retains heat far longer than unthickened broth, and creates a visually appealing translucent sheen. Applications range from ankake udon (thick udon in starch-thickened broth, warming in winter) to agedashi tofu (fried tofu in ankake dashi), to ankake kanikama crab sauce over tofu or steamed fish. The texture of well-made ankake is silky and flowing — it should coat a spoon in a thin translucent veil but not be gluey or stiff.

• Both Japanese ankake and Chinese cornstarch glazing use starch slurry to create coating, glossy sauces — Chinese cooking uses this technique more extensively in stir-frying, Japanese in soup finishing → Cornstarch velvet sauce and stir-fry finishing Chinese
• Both traditions use starch to create sauce body and coating ability, though Japanese starch-slurry method produces a lighter, clearer sauce compared to French roux's opaque richness → Beurre manié and roux thickening French

Smooth, silky, heat-retaining coating; the sauce flavour depends on the dashi base — clean umami in standard ankake, richer in crab or mushroom variations
