I don't drink much milk, and keep powdered milk in my staples cupboard at all times and use it in cooking. When I have whipping cream, I sometimes mix it, about 4 or 5 to one. My former father in law, ex military, lived 100 miles from the nearest commissary and used to freeze milk. I haven't tried this, but I do freeze butter. I would try freezing milk in ice cube trays and storing it in plastic bags as an alternative. There are many items that are readily available and are virtually industrictible that I keep in my kitchen for those rainy days. Powdered milk, dried mushrooms, small jars of mushrooms, boxed stocks, etc. I do not like to start cooking and have to make a run to the store for one small item.
