Garlic is rich in vitamin C, vitamin B6, and manganese. It also contains some calcium and phosphorus. Store whole heads of garlic in a cool, dry place in a bag or bowl with good airflow (such as a mesh bag or loosely woven basket). Keep it in your pantry or in a basket on your counter out of the sun. If you sliced a bunch of garlic for a recipe and have extra, store it in an airtight container in the fridge. Use it within 2-3 days.
