Kuzuyu (葛湯) is a sweet Japanese beverage that is made by adding kudzu flour to hot water.

In order to make Kuzuyu, Kudzu flour is added to hot water and stirred until thick.

Kudzu flour can also be used in East Asian sauces and soups, as it is a powerful thickening agent.

Though lacking fragrance and taste in its powder form, the arrowroot takes on a unique sweet flavor when dissolved in the hot water.

[1][11] Chik (칡) is the native Korean name of the plant, while cha (차; 茶) means "tea".

Galbun-cha is a Sino-Korean name for the drink, formed from gal (갈, 葛: the Korean pronunciation of the Chinese word for kudzu) and bun (분, 粉: the Korean pronunciation of the Chinese word for "flour, powder").

[11][13] Similar tea can also be made using starch powder from the scaly bulbs of Asian fawnlily.
