If milk has expired, this is not a reason to despair.
In addition to the well-known pancakes, there are a lot of other options for using the sour product.
Homemade cottage cheese
If you heat 1.5-2 liters of sour milk in a water bath, you can get 200-400 grams of homemade cottage cheese.

All you have to do is separate the whey from the curd mass and wait until the remaining liquid drains.
Marinade for meat
Sour milk is just as good for marinating meat as kefir.
Facial toner
Sour milk can be used for skin care. It has exfoliating properties and promotes collagen formation.
Pet food
Sour milk does not lose its beneficial properties, so you can simply give it to your cat or dog.
Cleaning silver
Simply soak your silverware in sour milk for half an hour and then rinse it under water to make it shine again.
