To tell the truth, many glutinous rice cakes don't need stuffing.
First of all, the method of making glutinous rice cakes is very simple. As long as the glutinous rice is steamed. Put it in a stone mortar. After the glutinous rice is beaten, it sticks together. It won't break if it is pulled for a long time. In this way, glutinous rice Baba is ready.
Of course, if you want to add any stuffing, for example. We all like the environment here. Or happen. Grind into fine powder and wrap it directly in glutinous rice cake. Some people make bean paste. Anyway, all kinds of fillings are just like jiaozi. You can add any flavor you like to make a ciba. Filling is just a process like wrapping jiaozi.
They are all places with many ethnic minorities. There are many solar terms every year. Almost every solar term is indispensable to eat. Take the Double Ninth Festival as an example. At that time, my heart had come out and I made Ciba with new glutinous rice. It tastes softer.
