1. Rinse the pan with water, and rinse all the inside of the pan with clear water before boiling milk.

2. Pour the milk into the pot slowly, and try not to touch the edge of the pot, which is easy to stick to the pot when heated.

3. It is not advisable to simmer with low fire, because dairy products cannot be heated at high temperature, otherwise the nutrition inside will be destroyed. Heat the pan with a small torch first. When the pan is hot, add hot milk. Don't burn too much, too much will burn to the side of the pot.

4. Stir continuously during heating. Keep winding it with a spoon, so it won't burn.

Milk doesn't have to wait until it boils, just see it steaming.
