Method of salad dressing

Preparation materials: 1 egg yolk, 17g vegetable oil, 2g white vinegar and 25g powdered sugar

Steps:

1. Put the egg yolk into a clean bowl without water and oil, and add 25g powdered sugar.

2. Beat evenly until the yolk becomes lighter.

3. Add a spoonful of oil.

4. Beat with an egg beater to completely blend the oil and egg yolk.

5. If it doesn't stir, add a little vinegar and continue to beat.

6. After adding vinegar, the sauce in the bowl will become thinner. At this time, the process of adding oil and stirring is repeated a few times. As the oil continues to be added, the sauce becomes thick again.

7. When the sauce becomes thicker, add a little white vinegar. Add vinegar when it is thick, add oil when it is thin, and repeat this process until both oil and vinegar are added.

8. mixing is completed.
