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 salad dressing 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
Refrigerate opened condiments and sauces with their lids on tightly, and use a clean spoon each time to avoid contamination. Store unopened cans in a cool, dry cupboard, and once opened, transfer leftover canned food to a covered container in the fridge rather than storing it in the can.
