Ingredients: milk, eggs, sugar

1. First, pour the milk into bowl A, heat it in the microwave oven until it boils, and let the milk cool. At this time, you can see that a thin layer of milk skin has formed on the surface of milk.

2. Beat the egg whites in Bowl B evenly (based on one egg white in each bowl), add sugar (put a few spoonfuls according to personal taste), and beat evenly with an egg beater until the egg whites bubble.

4. Then, open a small mouth at the edge of the milk skin, pour the cooled milk in bowl A into the big bowl, leave the milk skin in bowl A, and fully stir the milk, egg white and sugar in bowl B. As long as the egg foam is uniform, the milk and egg foam will dissolve together quickly.

5. Use a filter to remove a layer of foam powder on the surface, and then slowly pour the solution after removing foam powder back into bowl A. The milk skin originally left at the bottom of bowl A will float and cover the mixture.

6. Finally, put bowl A into the microwave oven and heat it for 5 minutes on low heat.

7, double skin milk out of the pot
