Does it happen to you that you sometimes look inside your fridge and discover milk or other dairy products which are not supposed to be used anymore, according to the date on the package? It sure happens to me sometimes. Here's what I do:
1. Check if it really has gone bad.
If it's only a day or two after the date on the package, often the product won't be bad at all.
2. Use it for cooking or baking.
I've found out that even if I won't add this milk to my coffee anymore, it can still be very good for pancakes or cookies.
3. Make cheese from it.
Homemade cheese is not very difficult to make and it's fun. And even if your attempt fails, at least you tried! I let it go really sour, and then cook it until it boils. I get a semi-liquid chunky mass which I then wrap in a cloth, wait, and let the water run down. And voila – homemade cheese.
4. Use it for a facial mask.
Mixing some milk with oatmeal (and maybe some honey) produces a wonderful mask, even though I admit it's a bit gross.
I'm sure I haven't discovered all possible uses for old milk. Waiting to hear your tips!
