Yogurt can't be made into double skin milk. Because yogurt is not suitable for heating, heating will destroy its nutritional value and affect the taste.

Double skin milk practice:

Half a catty of pure milk and an egg white.

1, put pure milk in a pot and boil it with low heat, and peel off the milk skin;

2. Egg whites and sugar are slowly stirred without foaming;

3. Pour the boiled milk into a bowl and let it cool slowly, and a layer of milk skin will appear. Punch the milk skin, pour the milk into the egg white, stir it slowly and evenly, then pour it into a bowl filled with milk skin, steam the bowl in a steamer for 10 minutes, poke it with chopsticks and take it out.
