Grind the sesame seeds into powder, add lard and sugar and mix thoroughly, then dry it into a cake shape, use a knife to score many horizontal and vertical lines, put it in the refrigerator, then take it out and break it into small cubes with your hands.
3. Then mix the rice dumpling powder with a small amount of water and knead it into a dough that is neither dry nor thin but very soft.
4. Let the dough rest for a while, then divide it into equal-sized pieces.
5. Shape the dough into a round shape and put a piece of filling on it, then wrap it up and set aside.
