Cake powder is not the same as white bean jelly. Cake powder uses flour, special rice flour or glutinous rice flour. For example, Sichuan Lianggao is made by grinding flour and rice flour (special for Lianggao) in warm water, soaking them in boiling alkaline water (lime water), and freezing them. White bean jelly is a famous snack in southern China, which is made of plant jelly glue and other raw materials. The product has the characteristics of tender and smooth quality, crystal clear, refreshing and delicious, and has a pleasant flavor. It is a good summer product. Its raw material is natural grass powder or starchy food.
