Cauliflower is one of several vegetables in the species Brassica oleracea, in the family Brassicaceae. It is an annual plant that reproduces by seed. Typically, only the head (the white curd) of aborted floral meristems is eaten, while the stalk and surrounding thick, green leaves are used in vegetable broth or discarded.

Its name is from Latin caulis (cabbage) and flower,[1] an acknowledgment of its unusual place among a family of food plants which normally produces only leafy greens for eating. Brassica oleracea also includes cabbage, brussels sprouts, kale, broccoli, and collard greens, though they are of different cultivar groups.

For such a highly modified plant, cauliflower has a long history. François Pierre La Varenne employed chouxfleurs in Le cuisinier françois.[2] They had been introduced to France from Genoa in the 16th century, and are featured in Olivier de Serres' Théâtre de l'agriculture (1600), as cauli-fiori "as the Italians call it, which are still rather rare in France; they hold an honorable place in the garden because of their delicacy",[3] but they did not commonly appear on grand tables until the time of Louis XIV.[4]

Classification and identification

Botanical varieties

Cauliflower and broccoli are the same species and have very similar structures, though cauliflower replaces the green flower buds with a white inflorescence meristem.

Major groups

There are four major groups of cauliflower.[5]

Italian 
Diverse in appearance, and biennial and annual in type, this group includes white, Romanesco, various green, purple, brown and yellow cultivars. This type is the ancestral form from which the others were derived.
Northwest European biennial 
Used in Europe for winter and early spring harvest, this was developed in France in the 19th century, and includes the old cultivars Roscoff and Angers.
Northern European annuals 
Used in Europe and North America for summer and fall harvest, it was developed in Germany in the 18th century, and includes old cultivars Erfurt and Snowball.
Asian 
A tropical cauliflower used in China and India, it was developed in India during the 19th century from the now-abandoned Cornish type,[6] and includes old varieties Early Patna and Early Benaras.

Varieties

A comprehensive list of varieties is maintained at North Carolina State University.[7] Traditional varieties include 'Snowball', 'Hybrid White', 'Super Snowball', 'Snow Crown', 'Mayflower', Candid Charm', 'Mormon', 'Agrahani', 'poushi', 'maghi', 'Snow White' and 'Snow Grace'.

Self-blanching varieties are 'Self Blanche', 'Early Tuscan' and 'Late Tuscan'.

Heirloom varieties include 'All the Year Round', 'Early Pearl', 'Early Snowball', 'Igloo', 'Violetta Italia' and 'Walcheren Winter'.

Commercial varieties include 'Fremont', 'Igloo' and 'Snow Crown'

Colors

White 
White cauliflower is the most common colour of cauliflower.
Orange 
Orange cauliflower (B. oleracea L. var. botrytis) contains 25 times the level of vitamin A of white varieties. This trait came from a natural mutant found in a cauliflower field in Canada.[8] Cultivars include 'Cheddar' and 'Orange Bouquet'.
Green 
Green cauliflower, of the B. oleracea botrytis group, is sometimes called broccoflower. It is available both with the normal curd shape and a variant spiky curd called Romanesco broccoli. Both types have been commercially available in the U.S. and Europe since the early 1990s. Green-curded varieties include 'Alverda', 'Green Goddess' and 'Vorda'. Romanesco varieties include 'Minaret' and 'Veronica'.
Purple 
Purple color in cauliflower is caused by the presence of the antioxidant group anthocyanins, which can also be found in red cabbage and red wine.[9] Varieties include 'Graffiti' and 'Purple Cape'. In Great Britain and southern Italy, a broccoli with tiny flower buds is sold as a vegetable under the name "purple cauliflower". It is not the same as standard cauliflower with a purple curd.

Cauliflower is low in fat, low in carbs but high in dietary fiber, folate, water, and vitamin C, possessing a high nutritional density.[citation needed]

Cauliflower contains several phytochemicals, common in the cabbage family, that may be beneficial to human health.

Boiling reduces the levels of these compounds, with losses of 20–30% after five minutes, 40–50% after ten minutes, and 75% after thirty minutes.[14] However, other preparation methods, such as steaming, microwaving, and stir frying, had no significant effect on the compounds.[14]

A high intake of cauliflower has been associated with reduced risk of aggressive prostate cancer.[15]

100g of cauliflower contains the following nutritional information according to the USDA:

  • Calories : 25
  • Fat: 0.28
  • Carbohydrates: 4.97
  • Fibers: 2
  • Protein: 1.92

Cooking

Aloo gobi, an Indian dish prepared with cauliflower and potato

Cauliflower can be roasted, boiled, fried, steamed or eaten raw. Steaming or microwaving better preserves anticancer compounds than boiling.[14] When cooking, the outer leaves and thick stalks are removed, leaving only the florets. The leaves are also edible, but are most often discarded.[16] The florets should be broken into similar-sized pieces so they are cooked evenly. After eight minutes of steaming, or five minutes of boiling, the florets should be soft, but not mushy (depending on size). Stirring while cooking can break the florets into smaller, uneven pieces. Cauliflower is often served with a cheese sauce, as in the dish cauliflower cheese.

Low carbohydrate dieters can use cauliflower as a reasonable substitute for potatoes; while they can produce a similar texture, or mouth feel, they lack the starch of potatoes.

Fractal dimension

Cauliflower has been noticed by mathematicians for its distinct fractal dimension,[17][18] predicted to be about 2.8.[19]

History

The first reliable reference to cauliflower is found in the writings of the Arab Muslim scientists Ibn al-'Awwam and Ibn al-Baitar, which date from the 12th and 13th centuries.[20]
