An onion is a bulbous vegetable that belongs to the Allium genus, known for its distinct layers and pungent flavor. It has a round or bulbous shape with papery, dry outer layers that can range in color from white and yellow to red or purple, depending on the variety. The inner layers are firm and crisp, with a white or off-white color.
When sliced or chopped, an onion releases a strong, characteristic odor that can make eyes tear. Its taste is sharp, tangy, and slightly sweet when raw, but when cooked, it becomes milder and sweeter, adding depth and flavor to various dishes.
