A large sweet onion with several regional names. May also be known as Spanish Onion, and possibly 1015 onion.
There are two main classifications of onion — green onions (also called scallions) and dry onions, which are simply mature onions with a juicy flesh covered with dry, papery skin. Dry onions come in a wide range of sizes, shapes and flavors. Among those that are mild flavored are the white or yellow Bermuda onion, available March through June; the larger, more spherical Spanish onion, which is usually yellow skinned (but can be white) and in season from August to May; and the red or Italian onion, which is available year-round.
