Step 1: Pour the strawberry milk into a container and bake it in the microwave oven for 30 minutes. If there is no cake-like milk, continue baking for a few minutes until it becomes cake-like milk.

Step 2: Pour pure milk into the container where yogurt will be cooked later, then add sugar and heat it in the microwave oven for 3 minutes. After taking out, add 3 teaspoons of baked strawberry milk and stir well.

Step 3: Put the water into a yogurt machine or rice cooker, with the scale of 2, cover and boil the water for 10 minutes, then put the yogurt down and cook for 8 hours.

Note: If you cook yogurt with a rice cooker, press the last step of the third step. If it is a yogurt machine, you can directly boil water with yogurt.
