Garlic
Yes, we know: Garlic is a vegetable (not a herb or spice), but it's most often used as a seasoning. It belongs to the same family of plants as onions, chives and leeks. Garlic's strong odor and taste make it a powerful addition to any dish, and it can take many forms in the kitchen. Fresh garlic tends to have the most robust flavor, but garlic powder and even garlic salt taste great and are common key ingredients in everything from dips to seafood dishes.
