Frozen food advice

Myth: You can freeze all foods.
While it’s true most edibles freeze under the right conditions, there are some that should never see the inside of your freezer. Delicate vegetables like lettuce practically disintegrate when they’re frozen then thawed. Creamy sauces that are frozen separate and “break” or curdle when thawed. Even coffee shouldn’t be stored in the freezer—especially dark roasts. The oils that make them so special break down in freezing temperatures, allowing the coffee to readily absorb off- flavors. The USDA also advises not to freeze canned goods or eggs in their shell. (But you can freeze canned goods if they are removed from their original packaging, as well as eggs as long as they are removed from their shell.)
