Most of us usually have a few sticks of butter and margarine in the refrigerator, or probably either one or the other as there seem to be two distinct camps out there. But, with butter and margarine it's not always easy to keep track of how long they've been there.

Are we keeping butter too long? Could you do a better job of keeping it fresh? Food scientists have several suggestions to help with all of these questions. Read all about them on the individual butter or margarine pages.
