Add a few drops of white vinegar to the egg whites and stir at low speed for half a minute.
5.
Add icing sugar in three times and stir until neutral foaming.
6.
Add the egg white batter to the egg yolk batter in two batches, and mix evenly from the bottom up, without making a circular motion.
7.
Finally, add the egg yolk paste to the egg white paste and mix evenly from the bottom up. Do not make a circular motion to avoid defoaming. Affect the taste.
8.
Spread the baking pan with cake paper, pour the batter into the baking pan, and shake it lightly.
9.
Preheat the oven and bake at 150 degrees for 20 minutes. My oven is 40 liters. Each oven has a different size. The set time and temperature are different. If the oven temperature is too small, it is best not to set too high to avoid baking. Too coke.
10.
While baking the cake, beat the whipped cream. The whipped cream is blown at high speed throughout the whole process, just like marshmallows.
