You don't need appetizers. I've been doing it these days. Just go to the supermarket and buy a box of original yogurt (there must be original yogurt! )。

1. Disinfect the utensils for making yogurt.

2. Pour the pure milk into the pot for boiling and sterilization, and add sugar at the same time (the amount of sugar is according to your own preferences).

3. When the milk is cooled to more than 30 degrees, pour the milk and yogurt into the vessel according to the ratio of 5: 1, and seal it for seven or eight hours, with the internal temperature around 30 degrees.

When the yogurt becomes sticky, it can be stored in the refrigerator.

Remember to save some yogurt for next time! ! ! )
