Onions

Onions are a bulbous vegetable belonging to the Allium family, which also includes garlic and leeks. They grow underground as a layered bulb composed of concentric rings, each made of fleshy leaf bases. Onions have a strong, pungent aroma and flavor due to sulfur compounds, which can cause eye irritation and tears when sliced. They are widely used in cooking to add depth and flavor to dishes, and their versatility allows them to be used raw, cooked, or caramelized. Nutritionally, onions are low in calories but rich in vitamins, antioxidants, and sulfur compounds that may offer health benefits.
