The importance of meat in medieaval Arab cuisine was such that vegetarian dishes were known as ‘counterfeit’ (مزوّرات, muzawwarāt) as they were intended to copy meat dishes, in an attempt to make the diner eat them! Non-meat dishes were associated with Christians (during Lent) and the sick. This 13th-century Andalusian recipe falls in the latter category and was allegedly useful against tertian and acute fevers (حُمَّى الغِبّ والحمّايات الحادّة). It is prepared by boiling and washing lentils and then cooking them with some gourd, chard, cucumber, vinegar, coriander, cumin, cassia and saffron. The resultant taste should be subtly sweet and sour, and the dish should be served cold.
