Onions are often chopped and used [as] an ingredient in various hearty warm dishes. [...] They are also used raw in cold salads.

Common onions are normally available in three colors: yellow, red, and white. Yellow onions are full-flavored and are a reliable standby for cooking almost anything. Yellow onions turn a rich, dark brown when cooked and give French onion soup its tangy sweet flavor. The red onion is a good choice for fresh uses or in grilling and char-broiling. White onions are the traditional onion used in classic Mexican cuisine. They have a golden color and sweet flavor when sauteed.

Onions are available in fresh, frozen, canned, caramelized, pickled, powdered, chopped, and dehydrated forms.
