The word baysar (بيسار) referred to dried broad beans (فول, ful) in medieval Andalus and North Africa, but also to a dish made with them. This recipe from The Exile’s Cookbook requires cooking the beans in water with some onion, garlic, cumin, coriander and fennel until It becomes a smooth mass, at which point salt is added. It was eaten with cumin and olive oil, and the author recommended rue, onions or olives as an accompaniment.
The dish has survived to the present day in the form of the bissara (بصارة) of Morocco, Algeria and Egypt, where it probably originated since the word, itself, goes back to the Coptic pesouro. It tends to be eaten for breakfast (especially in winter) or as a filling snack or dip with bread, and is still served with a sprinkling of cumin.
One can also draw parallels with other dishes such as the Egyptian national dish ful medammis (فول مدمّس) or the Cretan koukofava.
