Lupin are the yellow legume seeds of the genus Lupinus. They are traditionally eaten as a pickled snack food, primarily in the Mediterranean basin , Latin America (L. mutabilis) and North Africa (L. angustifolius). The most ancient evidence of lupin is from ancient Egypt, dating back to the 22nd century BC. The bitter variety of the beans are high in alkaloids and are extremely bitter unless rinsed methodically. Low alkaloid cultivars called sweet lupins have been bred, and are increasingly planted. The earliest archaeological reports on lupins are referred to the Twelfth Dynasty of Egyptian Pharaohs. In their tombs, seeds of Lupinus digitatus Forsk., already domesticated in those times, were discovered. Seven seeds of this species were also retrieved in the tombs of this dynasty dated back to the 22nd century BC. They are the most ancient evidence of lupin in the Mediterranean. Lupin is commonly used in Egypt (known by the name "termes") and is eaten by the Egyptians as snack anytime as during the Sham Elnesim festival, which is a national festival in Egypt whose history goes back to ancient Egyptian times. Lupin were also used by the Ancient Greeks and Romans.
