I hardly ever freeze anything. I mean, yeah, I freeze that I buy frozen and are supposed to be put in the freezer, like ice cream, frozen dinners, and, um, ice. But I've just never been the type of guy who freezes leftovers or freezes foods to be used for another day. I guess I'm a cook-it-and-eat-it guy.
AOL Food (from Real Simple) has a guide to everything you need to know about freezing though, including tips on how to prevent freezer burn (you can eat food that has freezer burn, just make sure you cut off the part that has the discoloration).
They also have a list of foods that should never be frozen, including cake batter, raw celery, corn on the cob, garlic, and mayonnaise. Though I can't even think of why you'd want to freeze mayonnaise. "Frozen Mayo" is a great name for a band though.
