1. Use rice flour or white flour, add water and yeast, live into a thin batter, and ferment for one night.
2. The next day, add salt to the fermented batter, chop the leeks and add them. If you don't like leeks, you don't have to eat them.
3. Put the special eggs on the fire (not too big) without turning the pot (many small shops selling daily necessities in Jiyuan sell them). After the pan is hot, oil it, put a spoonful of batter, cover the lid, and wait until the batter turns white and yellow, then you can go out of the pan.
4. Grease the eggs again, add salt and pour them into the pot, put the baked ones on, cover them, and wait until the eggs are cooked without turning over.
Ps: Of course, if you think it's too much trouble, you can just beat the eggs into batter and make it into egg batter.
