Cooking Steps

1. 

   Step1:It's better to refrigerate the eggs first, and then separate the egg yolk from the protein in two containers (the container for the protein should be deep, which is not easy to splash out and the container should be free of water and oil

2. 

   Step2:Put water, sugar 1 and salad oil into the egg yolk and beat them evenly, then sift them into low flour and mix them. Don't circle them and form particles easily. Put them aside after mixing

3. 

   Step3:Preheat oven at 150 ℃ for 5 minute

4. 

   Step4:Add a few drops of white vinegar to the egg white and beat it with the electric beater at a low speed for 1 minute. See the big bubbles in the eyes of the fish. Add one third of the sugar in the sugar 2. Beat it at a medium speed for about 1 minute. Then add one third of the sugar and beat it for another minute. Continue beating until the protein can be pulled up into an upright triangle. It's not too hard (you can feel the protein is fine with your fingers). Scrape the protein on the edge of the container How many times at low spee

5. 

   Step5:Mix one third of the protein into the egg yolk. Use a scraper to turn it in the opposite direction, mix it evenly, then add one third, then continue to turn it again, and finally put the remaining one third into the egg yolk and mix it evenly (the purpose of adding it in several times is to prevent defoaming

   Step6:It's easier to use flour on the wall of the cake mold to climb the cake, pour the cake liquid into the mold in a waterfall shape from top to bottom (this is to eliminate the big bubbles). After pouring, use a scraper to smooth the surface and shake the big bubbles from the height of more than ten centimeters

7. 

   Step7:Place the cake mould on the baking net at the bottom of the oven and heat it up and down for 130 ° 4050 minutes (depending on the maturity of the cake, observe that the color of the cake surface becomes darker and the baking time is close to the baking time. Insert the toothpick into the cake. If there is no attachment on the toothpick, it means that the cake is cooked. If there is slime or debris on the toothpick, it means that the cake is not cooked, the time can be extended or the temperature can be increased

8. 

   Step8:After the cake is baked, take it out and shake it twice from a high place to exhaust the hot air, then turn it upside down and cool it for 12 hours, and then demould it (too early demoulding will cause the waist to collapse
