Yangmei is a kind of glutinous rice dumpling, which is wrapped in brown sugar and sesame seeds and steamed with red glutinous rice. After steaming, its appearance is bright red like bayberry, the wall is sticky and soft, and the stuffing is sweet. There is also a gas slightly higher than the standard atmospheric pressure, and there will be an occasional "poof" when eating. Rice noodle snacks should be soft and glutinous, so we should pay attention to "hook back" rice noodles, which is the proportion of glutinous rice noodles and "early rice noodles". If there are too many glutinous rice noodles, it is difficult to make "glutinous rice noodles" although they are delicious. If there is too little glutinous rice flour, although it is easy to make, it will affect the taste.
