Garlic is one of the most widely used ingredients in cooking, known for its distinctive flavor and numerous health benefits. However, like any other food item, garlic can go bad if not stored properly or if it’s past its shelf life. But how do you tell if garlic has gone bad? In this article, we’ll delve into the world of garlic, exploring its characteristics, shelf life, and the signs that indicate it’s time to say goodbye to that clove.
Understanding Garlic and Its Shelf Life
Garlic is a member of the Allium family, which also includes onions, leeks, and shallots. It’s a bulbous plant with a papery outer layer covering several individual cloves. The shelf life of garlic depends on various factors, including the storage conditions, handling, and the variety of garlic.
