There is no scallion in it: the name comes from the pulled maltose-and-sugar candy, which is stretched and folded until it looks like hollow white scallion stalks.
Pieces of the pulled-sugar candy are laid on thin flour wrappers with crushed peanuts, sesame seeds and desiccated coconut, then folded up.
