What the freezer time means
Freezer times from USDA FoodKeeper are about quality, not safety. Food kept frozen at 0 F (-18 C) stays safe indefinitely; what changes over the months is texture, moisture and flavour. Wrap lettuce tightly, press out air, and label the pack with the date so the guideline above is easy to track.
Thaw in the fridge, not on the counter. Anything that thawed in the fridge can be refrozen, with some further loss of quality; anything left at room temperature for more than 2 hours should not go back in.
Storage habits that make the difference
Store leafy greens loosely wrapped in the crisper drawer, ideally with a paper towel to absorb extra moisture. Keep potatoes, onions and garlic in a cool, dark, dry place outside the fridge, and store potatoes away from onions since they spoil each other faster. Trim and wash vegetables just before cooking.
