1. Prepare the ingredients, and a sealed box, I use a bowl of instant noodles with sauerkraut
2. Boil water in a pot to blanch the bowl and spoon
3. Blanch the milk, just warm it up a little bit.
4. Pour the milk into the lunch box, add white sugar and stir evenly
5. Add two spoons of yogurt bought in the supermarket
6. well mixed
7. Close the lid
8. Put it on the floor with floor heating, cover it with a small mattress to keep it warm, and leave it on the floor to ferment overnight
9. Success, the prepared yogurt is very thick, the tofu is in the brain state
10. The spoon will not collapse, O(∩_∩)O haha~
Tips:There is no special technique, just make sure the container is clean. It needs to be scalded to kill bacteria that are harmful to fermenting bacteria. I made it at night and went to bed immediately. The next morning, it will be fine, sweet and sour. It's delicious~~ If you have heating at home, you must try it
