Lampreia (lamprey) is a very strange fish that, somehow, gained favor with emperors and kings. The Romans included it in banquets prepared for Julius Caesar. The oldest known Portuguese cookbook, a 16th century collection of recipes attributed to Infanta D. Maria, has a single fish recipe that describes how to prepare and cook lamprey.
You don’t have to conquer Gaul or marry royalty to eat lamprey. Many Portuguese restaurants offer this delicacy between January and April. It is usually served stewed, accompanied with rice. You find excellent lamprey at Solar dos Presuntos, a traditional Lisbon restaurant where you can dine like a king.
