Place the fish head pieces in a large bowl. Add the rest of the ingredients and mix with your hands, working the seasonings and spices into the fish flesh. Cover and allow to marinate in the fridge for a couple of hours.
Arrange the fish pieces in 2 to 3 shallow heatproof bowls. Top with leeks. Sprinkle with salt, if you like. Steam over briskly boiling water for 20 to 30 minutes.
Serve hot by itself or with rice.
