Raw materials: eggs, yogurt, flour, sugar.

Steps:

Step 1, beat the eggs, separate the egg white and egg yolk.

Step 2, add flour and yogurt to the egg yolks and stir. If you like it sweeter, you can add some sugar.

Step 3: Stir until grain-free.

Step 4: Add sugar to the egg whites in 3 batches and beat with a whisk.

Step 5: Here's a picture of the whisking process, stopping in the middle to add sugar.

Step 6, whipped, as shown. The whisk is pumped up and the whites are seen to set into a cone.

Step 7: Mix the egg yolk paste and egg whites in several batches. Slowly mix up and down with a spoon, not vigorously, otherwise it is easy to eliminate the egg white foam. You can add raisins, small nuts or cheese in this step, don't also delicious.

Step 8, mix well, as shown in the picture.

Step 9: Pour into the mold, shake gently and place on the steamer. If you added raisins or small nuts in the previous step, you can spoon some egg batter into the mold first in this step, and then gently spoon the raisins or small nuts onto the batter evenly. The consistency of the batter will determine if the raisins work the nuts in the center and bottom of the cake.

Step 10: Dish the lid on the cake mold, pay attention to reserve space for the cake to expand, cover the pot with a lid and steam the water for 30 minutes.

Step 11, after steaming, about boring 2 minutes. Eat ~(≧▽≦)/~ la la la!
