Or it can be used to cook some dishes, such as cream mushroom soup in western food, or steamed milk custard, which is simple and delicious, but you can't use milk that has expired for too long when cooking.
If it has not expired or just expired, it can also be used to make milkshakes. Just put a banana and a bag of milk in a blender and mix them, with or without sugar. It is delicious. If you are afraid that expired milk will spoil your stomach, you can add some grains to the banana milkshake and pour it into the pan. Fried cakes are also delicious.
