Bullinada Catalane

The sofregit is built first: Allium cepa is sliced and cooked in Olea europaea over very low heat for 45 minutes until completely caramelised and reduced — no hurrying this step. Ripe tomato concassé is added and cooked a further 30 minutes until the tomato is fully absorbed into the onion paste. Allium sativum is added at the end of the sofregit. Waxy potatoes (Solanum tuberosum — Charlotte or Nicola variety) are peeled and cut in 3cm rounds. Water and dry white wine (Collioure blanc or Roussillon white) are added to the sofregit; the potato rounds go in first and cook 15 minutes. Whole white-fleshed rockfish (Scorpaena porcus, Serranus cabrilla, or equivalent Tyrrhenian-Mediterranean species) are placed on top of the potato and cooked at a rolling boil for 12 minutes. A rouille — made without the cèpe addition of the Corsican version but with Piment d'Espelette instead of cayenne — is spread on grilled country bread and placed in the bowl. The broth is ladled over fish, potatoes, and bread at service.

Côte Vermeille and Roussillon coast, Pyrénées-Orientales — the Catalan-French bouillabaisse equivalent, made with potatoes, white-fleshed rockfish, and a Catalan sofregit base (slowly caramelised onion and tomato paste) rather than the aromatic broth approach of Marseille. The name is Catalan for 'boiled fish'. The preparation's ancestry lies in the same Phoenician-Greek colony trade networks that established Massalia (Marseille) to the northeast — the Greek colony of Ruscino (near modern Perpignan) was founded 300 years before Marseille and shared the same Mediterranean rockfish tradition that both cities cooked into fish soups.

The sofregit gives the Bullinada a depth that Marseille's bouillabaisse achieves through fish frame extraction — this is a different path to richness, via caramelised vegetable sweetness rather than marine protein. The potato absorbs the broth during cooking and acts as a secondary vehicle for flavour alongside the fish. The Piment d'Espelette rouille brings a gentle heat that sits with the sweet sofregit rather than opposing it.

The sofregit is the defining element — it must cook 45 minutes to full caramelisation, not 15 minutes to softening. A rushed sofregit gives a thin, sweet tomato-onion base; the fully caramelised version gives a deep, concentrated paste that enriches the entire broth. The potato must be waxy, not floury — it must hold its form in the rolling boil. The fish is placed on top of the potato, not stirred in — it cooks in the steam as much as the broth.

White-fleshed Mediterranean and Tyrrhenian rockfish: Scorpaena porcus (rascasse noire — the Catalan coast's primary rockfish), Serranus cabrilla (serran-chevrette), and Epinephelus marginatus (mérou brun) at Reserve tier. The Catalan coast's rockfish population differs from the Gulf of Lion species — Scorpaena porcus replaces Scorpaena scrofa as the primary species. Solanum tuberosum waxy variety — Charlotte or Nicola specifically; Bintje or floury potatoes are not appropriate.
