Operation method:
1. Shell the fresh eggs, add the white sugar, and beat them evenly with three or four chopsticks, first lightly, then heavily, then slowly, for about15 ~ 20 minutes, so that the liquid of the eggs can be fermented, foamed, thickened, milky white in color, and its volume is increased by one and a half to two times.
2. Mix the baking powder with the flour, pour it into the egg liquid, and stir it into a uniform paste. It is not advisable to stir it too much to prevent the flour from shrinking into pieces and make the cake loose.
3. Prepare a mold for steaming cakes, or a metal lunch box for ordinary families. Coat the bottom of the lunch box with a layer of crude oil to prevent it from sticking to the bottom. Then pour the stirred paste into the box and cook it in the pot. Steam with boiling water for three minutes, until the cake crust, then reduce the temperature (add some cold water in the pot), steam for about 10 minute, and the cake is formed; Add more fire until the cake is steamed. Spread some cooked oil on the surface of the cake when it is out of the pot, and you can eat it.
