Water chestnut flour is made from dried, ground water chestnuts. The nuts are boiled, peeled and then ground into flour. The flour, which is actually a starch rather than flour is white cream in colour. Its primary use is as a thickening agent and to make batters for deep frying in Indian and Asian cooking.
