How many times have you thrown out half a can of chicken broth or tomato paste because you only needed a small amount for the recipe you’re making? Or, perhaps you put it in the refrigerator, thinking that you would use it later. Instead, you found it in the back six months later when you finally got around to cleaning your fridge.
A better solution would be to freeze the leftovers. Ice cube trays come in handy for this purpose because you can freeze small amounts. Once they have frozen, transfer them to a freezer-proof bag.
Leftovers from your dinner can also be saved for later use. A few peas or potatoes may not seem like much, but added together, they make a great soup. If you also froze some bones from a pot roast or turkey, you will have everything you need.
