Fish Tagine with Chermoula — Hout M'chermel

Morocco (Essaouira, Agadir, Safi — the Atlantic coast chermoula-fish tradition; the defining preparation of the Moroccan seafood kitchen)

Hout m'chermel is the great preparation of the Moroccan Atlantic seaboard: firm white-fleshed fish — traditionally sea bass (Dicentrarchus labrax), grouper (Epinephelus marginatus), or monkfish (Lophius piscatorius) — marinated for one hour in green chermoula (Allium sativum, fresh coriander, cumin, paprika, preserved lemon rind, Olea europaea olive-oil, lemon juice), then layered in the tagine over a base of sliced Solanum tuberosum potato and Solanum lycopersicum tomato, topped with additional chermoula, olives, and preserved lemon quarters, braised covered for 20–30 minutes. The potato layer at the base absorbs the fish-chermoula juices and becomes the most flavour-concentrated element on the plate — in Essaouira restaurants, the potato is eaten last. The fish cooks by steam and residual heat: white-fleshed fish in a closed tagine moves from perfect to dry within a 5-minute window.

Served with khobz and couscous. The potato-chermoula base is scooped with bread while couscous absorbs the fish-infused sauce. A wedge of preserved lemon is the condiment: the preserved lemon rind from the tagine is eaten directly.
