Jiangmian does not mean white flour, it actually refers to the flour obtained from grinding jiangmian. Jiangmai is a kind of glutinous rice with viscosity, and the flour made from it is different from ordinary white flour, more viscous. For this reason, it is often used to make pastries, dumplings or glutinous rice. If you need to use jiangmai flour in cooking, it is better to buy special jiangmai flour rather than ordinary white flour.
