Cooking Steps

1. 

   Step1:All materials here. The first is the separation of egg yolk and protein. The protein should be put into a container without water or oil. The chocolate powder should be melted with hot water. Other materials are called ready to us

2. 

   Step2:Beat the yolk, milk and cooking oil evenly with the hand beater. Sift the flour into the mixed powder materials. Stir until the yolk paste without particles

3. 

   Step3:Beat albumen. Add sugar at the first time. Add it in three times. Beat until stiff foam

4. 

   Step4:Here's the mixture of egg yolk paste and protein. I think the zebra pattern must be based on the original Qifeng. So the mixing method is not repeated. In short, it's fast. Otherwise, it's easy to defoaming

5. 

   Step5:The mixed cake batter is divided into two parts. One part is mixed with the chocolate before mixing. Then take two spoons of the same size. Chinese soup spoon or a slightly larger iron spoon can be used. Put one spoonful of batter in the middle. Then scoop one spoonful of chocolate batter and fold it on top

6. 

   Step6:Repeat the previous step to pour out all the batters. This process needs some patience to shake out bubbles.

7. 

   Step7:Put it in the preheated oven. Bake it for about 10 minutes at 175 degrees. Then bake it for another 30 minutes at 160 degrees. It depends on my experience in the oven at home. I just changed the oven. I watched the oven finish the cake

8. 

   Step8:Take it out of the oven and shake it from about 20cm high to the top of the table to exhaust air to prevent collapse. Then buckle it on the grill and demould it after cooling. Isn't the grain of the finished product good?
