Bits and pieces...
1. If you have a few less-than-tasty apples, not rotten but lacking texture, it's easy to turn them into applesauce. Peel them, cut them up (no cores), and cook them in a slow cooker or on a low burner. Cook till they're fairly soft, then mash them with the back of a spoon. The process by which mealy apples can be reconstituted into decent applesauce would make a great homeschool science lesson. (It's all about cells.)
2. If you have a cup of orange marmalade, you can mix it with soy sauce, ginger, and garlic to make a good cooking sauce for four pork chops. If you have half a cup, you can do two pork chops. We found the recipe in a freezer-cooking download from $5 Dinners, and it is the best orange sauce we've tried--way better than recipes using frozen orange juice. There are variations of the recipe all over the Internet, but it's basically a smaller version of this recipe on the Smucker's website (but with soy sauce instead of teriyaki sauce).
3. If you have a few small, slightly stale dinner rolls, you can slice them into thirds or quarters, spresd them with garlic butter, and toast them to go along with spaghetti or stew.
