1, 4 eggs, yellow and egg white separated.

2. Beat the egg yolk evenly, add a little milk, salad oil, seasonings (such as concentrated orange juice, green tea powder, cocoa powder, etc., depending on your favorite) and a little low-gluten powder, and stir into a thin paste.

3. Add sugar to the egg white and beat it into cream with an eggbeater (this step is very important. If there is no eggbeater, you can also put baking powder directly).

4. Mix 2 and 3, pour them into the mold, drop them a few times, and shake out bubbles.

5. Preheat the oven for 10 minutes in advance, and then bake.

6. The baking temperature should not be too high, otherwise the surface will be cracked, and the low temperature of 150 degrees should be used. It takes more than 1 hour. You can stick chopsticks in the cake to observe.
