Taiwan Province fried chicken chops, like Badi chicken chops and Haoda chicken chops, are covered with what powder? What's your name? The grains are fragrant and crisp. Where can I buy them or buy them wholesale? The flour wrapped in flour needs sweet potato flour to stir-fry the special crispy Taiwan Province chicken chops.

Say it is worthless, haha

As for the supplier (Baidu found it, you can measure it yourself)

Sweet potato powder, also called sweet potato powder, is a powder made of sweet potato starch. Sweet potato powder is generally granular, with coarse particles and fine particles. Usually, coarse sweet potato powder is better bought at home. Sweet potato powder, like white powder, will be sticky when dissolved in water, but the viscosity of sweet potato powder is higher than that of white powder. Therefore, sweet potato powder is used less when thickening Chinese food, because the viscosity is difficult to control. Sweet potato powder is widely used to make Chinese dim sum. Sweet potato powder can also be used for cooking. After the marinated ribs are dipped in coarse sweet potato powder and fried, the sweet potato powder can present a crisp taste, and the granular skin can also bring visual effects.
