They are a popular Chinese dessert made from glutinous rice flour dough coated with sesame seeds before being deep-fried.
Rice flour gives these cookies a very fine texture, an also results in a gluten-free dessert. Letting the dough rest allows the flour to absorb moisture, making it less crumbly and easier to handle.
