It is very important to take pure milk instead of pasteurized fresh milk. Don't use pure milk from Mengniu Yili. Pure milk sterilized at high temperature by local fresh milk brand has a shelf life of about ten days, with a bag of 250ml.
Add sugar. It must be sugar, not fudge. I added a spoonful of stirring. Don't let it sink to the bottom of the bowl. I like sweets very much. Sweet milk is made here. I can add as much as I want.
Microwave, fire, one and a half minutes, the temperature is just right, you can drink it directly, don't let it go, it will go bad if it gets cold. Super simple!
