Dictionary Definition

frijol n : the common bean plant grown for the beans rather than the pods (especially a variety with large red kidney-shaped beans) [syn: kidney bean, frijole] [also: frijoles (pl)]

Extensive Definition

The common bean, Phaseolus vulgaris, is an herbaceous annual plant domesticated independently in ancient Mesoamerica and the Andes, and now grown worldwide for its edible bean, popular both dry and as a green bean. The leaf is occasionally used as a leaf vegetable, and the straw is used for fodder. Botanically, the common bean is classified as a dicotyledon. Beans, squash and maize constituted the "Three Sisters" that provided the foundation of Native American agriculture. As a legume, beans provided the nitrogen-fixing bacteria which supplied that essential nutrient to the other two crops.

Description

The common bean is a highly variable species with a long history. Bush varieties form erect bushes 20 – 60 cm tall, while pole or running varieties form vines 2 – 3 m long. All varieties bear alternate, green or purple leaves, divided into three oval, smooth-edged leaflets, each 6 – 15 cm long and 3 – 11 cm wide. The white, pink, or purple flowers are about 1 cm long, and give way to pods 8 – 20 cm long, 1 – 1.5 cm wide, green, yellow, black or purple in color, each containing 4 – 6 beans. The beans are smooth, plump, kidney-shaped, up to 1.5 cm long, range widely in color, and are often mottled in two or more colors.
As the common bean is a dicot, it germinates as such:
  • The primary root emerges through the seed coats while the seed is still buried in the soil.
  • The hypocotyl emerges from the seed coats and pushes its way up through the soil. It is bent in a hairpin shape — the hypocotyl arch (Crozier's hook) — as it grows up. The two cotyledons protect the epicotyl structures — the plumule — from mechanical damage.
  • Once the hypocotyl arch emerges from the soil, it straightens out. This response is triggered by light (phototropism). While this may be caused by most wavelengths of light, the critical photoperidic mechanism is sensitive to red or far red light. This mechanism is crucial, not only to Phaseolus beans, but to most flowering plants. It defines the phenology of their growth, and in some cases growth habits.
  • The cotyledons spread apart, exposing the epicotyl, consisting of two primary leaves and the apical meristem.
  • In many dicots, the cotyledons not only supply their food stores to the developing plant but also turn green and make more food by photosynthesis until they drop off.

Nutrition and preparation

Toxicity

Before they are eaten, the raw bean seeds should be soaked in water several hours, boiled for at least ten minutes in new fresh water to degrade a toxic compound - the lectin phytohaemagglutinin - found in the bean which would otherwise cause severe gastric upset. This compound is present in many varieties (and in some other species of bean), but is especially concentrated in red kidney beans and white kidney beans (Cannellini beans). Although in the case of dry beans the ten minutes required to degrade the toxin is much shorter than the hours required to fully cook the beans themselves, outbreaks of poisoning have been associated with the use of slow cookers whose low cooking temperatures may be unable to degrade the toxin. Sprouts of pulses high in haemaglutins should not be eaten. Kidney beans, especially, should not be sprouted.

Dry beans

Similar to other beans, the common bean is high in starch, protein and dietary fiber and is an excellent source of iron, potassium, selenium, molybdenum, thiamine, vitamin B6, and folic acid.
Dry beans will keep indefinitely if stored in a cool, dry place, but as time passes, their nutritive value and flavor degrade and cooking times lengthen. Dried beans are almost always cooked by boiling, often after having been soaked for several hours. While the soaking is not strictly necessary, it shortens cooking time and results in more evenly textured beans. In addition, discarding one or more batches of soaking water leaches out hard-to-digest complex sugars that can cause flatulence, though those who eat beans regularly rarely have difficulties with flatulence as intestinal flora adjust. There are several methods including overnight soaking, and the power soak method, which is to boil beans for three minutes, then set them aside for 2-4 hours, then drain and discard the water and proceed with cooking. Common beans take longer to cook than most pulses: cooking times vary from one to four hours but are substantially reduced with pressure cooking. The traditional spice to use with beans is epazote, which is also said to aid digestion. Kombu, a type of seaweed, can be added to beans as they cook to improve their digestion as well. Salt, sugar, and acidic foods like tomatoes may harden uncooked beans resulting in seasoned beans at the expense of slightly longer cooking times.
Dry beans may also be bought pre-cooked and canned as refried beans, or whole with water, salt, and sometimes sugar.

Green beans

Green common beans are also called string beans, stringless beans (depending on whether the pod has a tough, fibrous "string" running along its length), or snap beans. Compared to the dry beans, they provide less starch and protein, and more vitamin A and vitamin C. The green beans are often steamed, stir-fried, or baked in casseroles.

Shelling beans

As with other beans, prominent among them lima beans, soybeans, peas, and fava beans, common beans can be used for fresh shell beans, also called shelling beans, which are fully mature beans harvested from the pod before they have begun to dry.
Nutritionally, shell beans are similar to dry beans, but in the kitchen are treated as a vegetable, often steamed, fried, or made into soups.

Popping beans

The nuña is an Andean subspecies, Phaseolus vulgaris subsp. nunas (formerly Phaseolus vulgaris (Nuñas Group)), with round multicolored seeds which resemble pigeon eggs. When cooked on high heat, the bean explodes, exposing the inner part, in the manner of popcorn and other puffed grains.

Varieties

Many well-known bean varieties belong to this species, and none of the lists below are in any way exhaustive. Both bush and running (pole) varieties exist. The colors and shapes of pods and seeds vary tremendously.

Snap or String beans

Stephen Facciola's Cornucopia lists 130 varieties of snap beans. Varieties specialized for use as green beans, selected for the succulence and flavor of their pods, are the ones usually grown in the home vegetable garden, and many varieties exist. Pod color can be green, golden, purple, red, or streaked. Shapes range from thin "fillet" types to wide "romano" types and more common types in between. French Haricots verts (green beans) are bred for flavorful pods.
  • Blue Lake (green)
  • Golden Wax (golden)
  • Purple King (purple)
  • Dragon's Tongue (streaked)
  • Red Swan (red)

Shell beans

Cornucopia lists 37 varieties of shell beans. The light green Flageolet bean is taken very seriously in France and soon the heirloom Chevrier will come under a controlled label reminiscent of the wine "Appellation d'Origine Controllée" called "Label Rouge". A number of other beans are already produced under this label.
Flageolet bean varieties include:
  • Chevrier (the original heirloom)
  • Elsa
  • Flambeau
  • Flamingo
Borlotti beans are dried beans. They originated in North America where they are known by several names. The bean is a medium large tan bean, splashed with red/black to magenta streaks. It is very popular in Italian and Portuguese cuisine.
The American cranberry bean or horticultural bean is quite similar if not the same as the Italian borlotti bean. Pinto beans are not considered the same as borlotti beans.
  • True Cranberry (old VT heirloom with a more round shape like a cranberry), traditional ingredient of succotash

Pinto or mottled beans

The pinto bean (Spanish: frijol pinto, literally "painted bean") is named for its mottled skin (compare pinto horse), hence it is a type of mottled bean. It is the most common bean in the United States http://www.ars-grin.gov/npgs/cgc_reports/phascgc.htm and northwestern Mexico http://www.siea.sagarpa.gob.mx/Publicaciones/Archivos/Frijol90-00.pdf, and is most often eaten whole in broth or mashed and refried. Either whole or mashed, it is a common filling for burritos. The young pods may also be used as green beans.
In the southwest United States, the pinto bean is an important symbol of regional identity, especially among Mexican Americans. Along with the chile/chilli, it is one of the official state vegetables of New Mexico (under the name frijol). The prepared beans are commonly known as frijoles. This type of bean is also referred to as "Cowboy Beans" in Texas, all along the Mexican border and wherever Mexican cowboys were employed. In areas where Mexican cowboys did not travel on the trails north from Texas, it was probably not known.
This is the most commonly used bean used for refried beans (fresh or canned), the bean used in Taco Bell menu items, and in many dishes at Tex-Mex restaurants. Rice and pinto beans served with cornbread or corn tortillas are often a staple meal where there is limited money for meat, as the combination of beans and corn creates virtually all the protein amino acids needed in a meat substitute. http://www.nps.gov/band/historyculture/ancestral-pueblo-farming.htm When it comes to making chili, if a bean is added, this is the one typically the one used, although the kidney bean, black bean, and many others may also be used in other locales (see below).
Pinto bean varieties include:
  • Sierra
  • Burke
  • Othello
  • Maverick
The alubia pinta alavesa, or the "Álava pinto bean", is a red variety of the pinto bean which originated in Añana, a town and municipality located in the province of Álava, in the Basque Country of northern Spain. In October, "la Feria de la alubia pinta alavesa" (the fair of the Alubia pinta alavesa) is celebrated in Pobes.
Another popular mottled bean is the anasazi, one of a number of more recently developed "gourmet" beans.

White beans

The small, white navy bean, also called pea bean or haricot, is particularly popular in Britain and the US, featuring in such dishes as baked beans as well as in various soups.
Navy bean varieties include:
  • Robust
  • Rainy River
  • Michelite
  • Sanilac
Other white beans are Cannellini and Great Northern.

Red (kidney) beans

The kidney bean with its dark red skin is named for its visual resemblance to a kidney. The kidney bean is also known as the red bean, although this usage can cause confusion with other red beans. Red kidney beans (rājmā in Hindi and Punjabi) are an integral part of the cuisine in northern region of India. Sometimes kidney beans are used in the red beans and rice of Louisiana Creole cuisine. Other times small red beans are used. Small red beans are noticeably smaller and darker than kidney beans. They have a smoother taste and are preferred for Cajun cuisine. Small kidney beans used in La Rioja, Spain, are called Caparrones.

Black beans

The small, shiny black turtle bean is especially popular in Latin American cuisine. It is often called simply the black bean (frijol negro in Spanish, feijão preto in Portuguese), although this can cause confusion with other black beans.
The black turtle bean has a dense, meaty texture and flavor reminiscent of mushrooms, which makes it popular in vegetarian dishes such as the Mexican-American black bean burrito. It is a very popular bean in various regions of Brazil, and is used in the national dish, feijoada. It is also a principal ingredient of Platillo Moros y Cristianos as in Cuba, served elsewhere in almost all Latin America.
Black turtle beans have recently been reported to be an extremely good source of nutritional antioxidants.
Black turtle bean varieties include:
  • Domino
  • Black Magic
  • Blackhawk
  • Nighthawk

Pink beans

Pink beans are small oval-shaped beans, pale pink in color, also known by the Spanish name Habichuelas Rosadashttp://www.recipetips.com/glossary-term/t--36058/pink-bean.asp. The most famous pink bean is the Santa Maria pinquito (spanglish = pink and small(ito) which is commercially grown on the mesas above Santa Maria, California, and is a necessary ingredient in Santa Maria Tri-tip barbecue.

Yellow beans

Sinaloa Azufrado, Sulphur, Mayocoba, and Peruano are types of yellow beans.
