A delicious 10th-century Abbasid recipe for a ‘cold dish’ (bārida), made with watercress, parsley, leeks, fish, and eggs, spiced with pepper, coriander, cumin, and caraway. Of note is the fact that you need to extract the juices from the herbs after crushing them. You can also make three dishes by making it with one of the herbs in separate pots. The fish should be boned — or you can just use fillets, of course!
