Here are a few things you need to know about storing garlic: .A whole, unpeeled garlic head will last quite a while (about six months).But an unpeeled clove that has been separated from the head will only stay good for about three weeks. .And don't even think about chopping or mincing the garlic unless you plan to use it ASAP.The best place for a whole head of garlic is somewhere cool, dry, and dark...but not the fridge.Whole garlic should be stored between 60°- 65°F, and for most people, the pantry is a good spot.But peeled or chopped garlic is a different story, and refrigeration is now the best storage solution.Seal it up in an airtight container or zip-top bag, and it will be fine to use for about one week.
