Broad Beans - Composition and Cultivation

Vicia faba, the Broad Bean, Fava Bean, Field Bean, Bell Bean or Tic Bean, is a species of bean (Fabaceae) native to north Africa and southwest Asia, and extensively cultivated elsewhere.

A variety is provisionally recognized:

Vicia faba var. equina Pers. – Horse Bean

Although usually classified in the same genus Vicia as the vetches, some botanists treat it in a separate monotypic genus Faba.

Composition

It is a rigid, erect plant 0.5-1.8 m tall, with stout stems with a square cross-section. The leaves are 10–25 cm long, pinnate with 2-7 leaflets, and of a distinct glaucous grey-green color; unlike most other vetches, the leaves do not have tendrils for climbing over other vegetation. The flowers are 1-2.5 cm long, with five petals, the standard petal white, the wing petals white with a black spot (true black, not deep purple or blue as is the case in many “black” colorings, and the keel petals white. Crimson flowered broad beans also exist, which were recently saved from extinction. The fruit is a broad leathery pod, green maturing to blackish-brown, with a densely downy surface; in the wild species, the pods are 5–10 cm long and 1 cm diameter, but many modern cultivars developed for food use have pods 15–25 cm long and 2–3 cm thick. Each pod contains 3-8 seeds; round to oval and 5–10 mm diameter in the wild plant, usually flattened and up to 20–25 mm long, 15 mm broad and 5–10 mm thick in food cultivars. Vicia faba has a diploid (2n) chromosome number of 12 (6 homologous pairs). Five pairs are acrocentric chromosomes and 1 pair is metacentric.

Cultivation

Broad beans have a long tradition of cultivation in Old World agriculture, being among the most ancient plants in cultivation and also among the easiest to grow. It is believed that along with lentils, peas, and chickpeas, they became part of the eastern Mediterranean diet in around 6000 BC or earlier. They are still often grown as a cover crop to prevent erosion, because they can over-winter and because as a legume, they fix nitrogen in the soil. These commonly cultivated plants can be attacked by fungal diseases, such as rust (Uromyces viciae-fabae) and chocolate spot (Botrytis fabae). It is also attacked by the black bean aphid (Aphis fabae).

This means it can withstand rough climates, and in this case, cold ones. Unlike most legumes, the broad bean can be grown in soils with high salinity. However, it does prefer to grow in rich loams.

In much of the Anglophone world, the name broad bean is used for the large-seeded cultivars grown for human food, while horse bean and field bean refer to cultivars with smaller, harder seeds (more like the wild species) used for animal feed, though their stronger flavour is preferred in some human food recipes, such as falafel. The term fava bean (from the Italian fava, meaning “broad bean”) is usually used in English speaking countries such as the US, however the term broad bean is the most common name in the UK.

Culinary uses

Broad beans are eaten while still young and tender, enabling harvesting to begin as early as the middle of spring for plants started under glass or over-wintered in a protected location, but even the main crop sown in early spring will be ready from mid to late summer. Horse beans, left to mature fully, are usually harvested in the late autumn. The young leaves of the plant can also be eaten either raw or cooked like spinach.

The beans can be fried, causing the skin to split open, and then salted and/or spiced to produce a savory crunchy snack. These are popular in China, Colombia, Peru (habas saladas), Mexico (habas con chile) and Thailand (where their name means “open-mouth nut”).

Broad bean purée with wild chicory is a typical Puglian dish in Italy.

In the Sichuan cuisine of China, broad beans are combined with soybeans and chili peppers to produce a spicy fermented bean paste called doubanjiang.

In most Arab countries, the fava bean is used for a breakfast dish called ful medames.

Fava beans are common in Latin American cuisines as well. In central Mexico, mashed fava beans are a common filling for many corn flour-based antojito snacks such as tlacoyos. In Colombia they are most often used whole in vegetable soups. Dried and salted fava beans are a popular snack in many Latin countries

In Portugal, a fava bean (usually referred to as fava in Portuguese) is included in the bolo-rei (king cake), a Christmas cake. Traditionally, the person who gets fava has to buy the cake the following year.

In the Netherlands, they are traditionally eaten with fresh savory and some melted butter. When rubbed the velvet insides of the pods are a folk remedy against warts.

Broad beans are widely cultivated in the Kech and Panjgur districts of Balochistan Province in Pakistan, and in the eastern province of Iran. In the Balochi language, they are called bakalaink, and baghalee in Persian.
