Every two weeks I throw away unused milk. We rarely drink it and yet I need it on hand for cooking. A few times I put the nearly-full container in the freezer thinking I could unthaw it if needed. That does not work too well because I usually only need a half cup or so. To unthaw the whole jug for such a little bit takes forever and then I end up tossing the rest anyway.
So today I decided to freeze it in muffin tins. Each tin holds 1/3 cup of milk.
After it was frozen, I ran the bottom under hot water for a few seconds and each cube popped right out.
I put them in a freezer bag inserted inside a plastic container.
Look at all those tiny one-third cup portions just waiting to be needed. They will thaw in no time at all.
