Second, the practice is as follows:

Materials:

4 eggs, yogurt 1 cup (100g), 70g flour, 40g sugar and 2 tbsps cooking oil.

Production steps:

1. First, put the egg whites and egg yolks in a clean and dry pot.

2. First, mix the egg yolk paste: add half a sugar, 2 tablespoons oil and a box of yogurt to the egg yolk. Add 70 grams of flour and mix well.

Mix it up.

3. Put the yolk paste aside and stir the egg whites. Start to send it in the same direction, and add half the remaining sugar when it is thick. Beat until wet and foaming, then add the remaining sugar to send it away.

4. Just make a small vertical angle.

5. Mix the egg whites with the yolk paste. Mix the egg white into the yolk paste three times, stir it up and down like cooking, and turn the pot.

Pour it into the cake mold and shake it twice to let the bubbles escape.

6. Wrap the plastic wrap and steam for 30 minutes.

Note: control the temperature and time.
