I use this recipe every time for the original cake roll. The recipe tastes good and is not easy to crack. Serving size - baking tray 28 * 28cm. There are many reasons for cracking - wet beat of protein. Don't beat too much; over high baking temperature, too long baking time, too hard baking on the skin. It will crack; roll when it's warm. Don't be too hot. Don't roll again when it's cold. At the same time, pay attention to prevent the skin from sticking off.
Step1:Separate protein and egg yolk into two basins. The basin containing protein must be free of oil and water. After separation, no egg yolk is allowed in the basi
Step2:Pour oil and water into the basin. Stir until the oil and water mix
Step3:Then add the yolk and mix well. After sifting with low powder, add and mix well
Step4:Add lemon juice or white vinegar to the protein. Beat the protein to the state of fish eye follicle. Pour in half of the white sugar
Step5:Continue to deliver the protein to a thick consistency. When it is thinner, pour the remaining 1/2 sugar into it
Step6:Continue to beat until the foam is wet. Lift up the eggbeater. It is in a hook state.
Step7:Put one third of the egg white into the egg yolk paste bowl. Turn over with a rubber scraper and mix well. Then pour in all the remaining egg white. Stir well.
Step8:Pour the cake paste into the baking tray paved with oil paper, shake the baking tray on the table for several times, and shake out big bubbles
Step9:Preheat the oven in advance. 170 degrees. Middle layer. Bake for 25 minutes. Bake until the surface is golden. (adjust the temperature and time according to your oven. If the novice can't judge the maturity, he feels that the cake is almost baked. Press lightly on the surface of the cake with his hand. The surface is a little hard. If you press lightly, the cake will come out. Do not open the oven door for a long time and often during baking.)
Step10:After baking, shake on the table with the baking tray. Then take out the cake together with the oil paper and put it on the baking net for heat dissipation. Take a piece of oil paper again and cover it. Then turn the whole cake over. Spread jam on it. Roll it up and set it. Some warm time roll. Don't wait for cool through
