The yellow onion or brown onion (Allium cepa L.[1][2]) is a variety of dry onion with a strong flavour. They have a greenish-white,[3] light yellow,[4] or white inside;[5] its layers of papery skin have a yellow-brown or pale golden colour.[3][4] It is higher in sulphur content than the white onion, which gives it a stronger, more complex flavour.[5][6] A dozen varieties of yellow onion are grown, following the time of year. They vary in nutritional content, but they do contain quercetin (a flavonol).[1] Yellow onions are typically available throughout the year,[4] grown between spring and fall, and then stored for the rest of the year.[4] It is the most commonly grown onion in northern Europe,[2] and it makes up 90% of onions grown in the United States.[4] They should be stored at cool room temperature in a dark place. Longer-term storage requires them to be wrapped in paper and placed in a refrigerator. Cut or peeled onions also need to be stored in plastic in the refrigerator, but they will last only a few days.[4] They have a rich onion taste and are fit for dishes such as French onion soup, other soups, stews and braises, sautéed dishes, and shish kebabs.[5] They can become sticky and sweet when caramelized.[4]
