Sweet potato starch is produced by pulverizing the sweet potatoes, sequentially wet-sieving and separating it into the starch. It is a popular starch used in Sichuan cuisine, but it is not a good option for thickening since the stickiness is quite strong.

Ideal for adding a coating & moistness to water boiled dishes. It can also help to create a lovely chewy texture when cooked with water.

Due to its smooth texture and toughness, it is also very suitable for noodles.

Sweet potato starch can also be used for frying.
