What is Onion?
The onion is a bulb vegetable, meaning its bulb and not its leaves are eaten. Onions come in many varieties, including white, yellow and red. Shallots are small and mild onions. Vidalias are sweet, while red onions are strong and sharp. The onion is usually round and has a thin dry skin around its juicy layers. This skin depends in the color of the onion, as does the flesh. The flesh, or body of the onion is made of multiple round layers, that get smaller towards the center. The flavor of onions are sharp and sweet when raw, with an astringent taste. When cooked, these flavors mellow and the sweetness emerges. Onion are a very common flavoring and ingredient for many savory dishes.
