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. ×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. In the autumn (or in spring, in the case of overwintering onions), the foliage dies down and the outer layers of the bulb become dry and brittle. The crop is harvested and dried and the onions are ready for use or storage. The crop is prone to attack by a number of pests and diseases, particularly the onion fly, the onion eelworm, and various fungi cause rotting. Some varieties of A. cepa, such as shallots and potato onions, produce multiple bulbs.
Onions are cultivated and used around the world. As a food item, they are usually served cooked, as a vegetable or part of a prepared savoury dish, but can also be eaten raw or used to make pickles or chutneys. They are pungent when chopped and contain certain chemical substances which irritate the eyes.

    Modifying a Chickpea, Onion and Chopped Tomato Curry to include Aubergine

    I saw this recipe on a tin of East End chickpeas that I bought from Waitrose. I'm thinking of doubling the tomatoes and adding an aubergine with just a 50% increase in the chickpeas. Can I just slice it the aubergine and add it or should I stab it a few times with a knife or fork then roast to...

It takes about 25-30 minutes total time...

    Recipe Keralan style tomato curry

    Keralan cooking often uses tamarind and coconut milk in curry dishes. This particular dish doesn’t include coconut milk but has a hot, sour and aromatic flavour reminiscent of Keralan cuisine. To me, one important thing here is the slicing of the onions and tomatoes into ‘petals’. If you simply...
