1. Prepare materials. 20g pudding powder, 200g milk, 20g sugar.

2. Pour 50g milk and 20g pudding powder into the basin and stir evenly.

3. Boil the remaining milk in a non-stick pan until it bubbles, and then pour the boiled milk into the basin in the first step.

4. Stir the milk and pudding powder in the basin evenly. You can also boil the milk again at a safe point, and the pudding will coagulate better.

5. Pour the milk into the container and put it in the refrigerator.

6. You can take it out and eat it the next day.
