1. In the morning, make the leftover bean dregs of soy milk, add flour, sugar, and water and stir evenly until there are no particles, not too dry.
2. Put the oil in the non-stick pan (optional) and add the batter.
3. Turn it over and continue frying for a while.
4. Pick up the pot and put it on the plate, add water to the steamer, and steam the cake for 15 minutes (in case the bean dregs are not cooked, and the steamed children will not get so hot after eating).
5. Ready to eat.
6. Black soy milk.
