freezer zip-lock bags are the cats meow!

hey everyone:

i have been using my freezer space with a whole new vigor lately. i also have had some pretty good success freezing things i hadn't thought of before, to have around for later, so i don't have to go to the store so often. i want everybody to add to this list if you have heard of or had luck with freezing things...

lemon juice (in ice-cube trays)
ginger (whole chunks of root)
milk (just make sure it thaws all the way and you shake it before use)
butter
bell pepper
cookie dough
nuts
grated cheese (whole blocks are kinda wierd after thawing)

go ahead - whachya got?
