Katakuriko 片栗粉

Katakuriko is potato starch or potato flour. Although the name ‘katakuriko’ traditionally referred to a flour made from the root of a variety of lily grown only in Japan, nowadays ‘katakuriko’ is commercially made from potatoes. It is used as a thickener, but you can replace it with cornflour/cornstarch or arrowroot without any significant change in flavour or texture.
