Katakuriko — Potato Starch and Its Uses

Japan-wide — potato starch production from Hokkaido

Katakuriko (片栗粉, 'potato starch') is the Japanese kitchen's primary thickening and coating starch — used for ankake sauce thickening, karaage (Japanese fried chicken) coating, agemono dusting, and as a binding agent in various preparations. Despite the historical name (katakuri refers to the dogtooth violet plant whose starch was the original source), modern katakuriko is made from potato starch — transparent, neutral in flavour, with exceptional thickening power and the ability to produce a more translucent, glossy gel than cornstarch. Key applications: ankake sauce thickening (produces cleaner, more translucent sauce than cornstarch); karaage coating (potato starch alone or mixed with flour creates a crispier, more delicate crust than all-flour coatings); gyoza wrappers (small amounts improve texture); and mochi-type confectionery where it is used as an anti-sticking powder on surfaces.

Flavourless as an ingredient; creates translucent, glossy coatings and sauces that allow the flavour of other ingredients to show through unmasked — the starch is purely textural and visual in function
