Not even in the freezer, we're afraid. Though it's technically true that food will remain safe to eat indefinitely after it's been frozen (except if it's been refrozen — read on to find out more), eventually it will definitely stop tasting great. We'll bet it's time for a cleanout at your place.

Admit it: Yours taste like fish. Ice cubes aren't impervious to food smells, and once they're stinky, there's no way to un-stink 'em. Rotate in new cubes regularly, and wash the trays after the last cube is gone.

This might be surprising, but ground coffee actually holds up better in the freezer than whole beans, which lose most of their flavor quickly when frozen. Plus, grinding still-frozen beans is an easy way to make your grinder rust.

Sure, you can cut off the damaged bits and hope for the best, but it's likely that "the best" will barely impress — you might as well start fresh. In the future, wrap things well, and try to open the freezer door as little as possible to prevent the fluctuations that lead to freezer burn.
