The lentil (Lens culinaris or Lens esculenta) / Lentil Beans is an edible legume. It is an annual plant known for its lens-shaped seeds. It is about 40 cm (16 in) tall, and the seeds grow in pods, usually with two seeds in each. As a food crop, the largest producer is Canada, producing 45% of the world’s total lentils.
Lentil Beans are used around the world for culinary purposes. In cuisines of the Indian subcontinent, where lentils are a staple, split lentils (often with their hulls removed) known as dal are often cooked into a thick curry/gravy that is usually eaten with rice or rotis. Elsewhere, such as in Iran, Ethiopia, the Americas and Europe, lentils are used in stews and soups.
Many different names in different parts of the world are used for the crop lentil. The first use of the word lens to designate a specific genus was in the 17th century by the botanist Tournefort. The word “lens” for the lentil is of classical Roman/Latin origin: McGee points out that a prominent Roman family took the name “Lentulus“, just as the family name “Cicero” was derived from the chickpea, Cicer arietinum, or “Fabia” (as in Quintus Fabius Maximus) from the fava bean (Vicia faba).
Types can be classified according to their size, whether they are split or whole, or shelled or unshelled. Seed coats can range from light green to deep purple, as well as being tan, grey, brown, black or mottled. Shelled lentils show the colour of the cotyledon which can be yellow, orange, red, or green.
