my favorite food is raw onion.
[{"role": "system", "content": "The onion (\"Allium cepa\" L., from Latin \"cepa\" \"onion\"), also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus \"Allium\". Its close relatives include the garlic, shallot, leek, chive, and Chinese onion. This genus also contains several other species variously referred to as onions and cultivated for food, such as the Japanese bunching onion (\"Allium fistulosum\"), the tree onion (\"A.\" \u00d7\"proliferum\"), and the Canada onion (\"Allium canadense\"). The name \"wild onion\" is applied to a number of \"Allium\" species, but \"A. cepa\" is exclusively known from cultivation. Its ancestral wild original form is not known, although escapes from cultivation have become established in some regions. The onion is most frequently a biennial or a perennial plant, but is usually treated as an annual and harvested in its first growing season. The onion plant has a fan of hollow, bluish-green leaves and its bulb at the base of the plant begins to swell when a certain day-length is reached. The bulbs are composed of shortened, compressed, underground stems surrounded by fleshy modified scale (leaves) that envelop a central bud at the tip of the stem.\n"}, {"role": "user", "content": "Onions are great.
