Originating in the coastal area of the Basque Country, ttoro is a traditional fish stew consisting of different types of fish and seafood cooked in fish stock with vegetables and aromatic herbs, and flavored with piment d’espelette (local red pepper).
From a humble fisherman’s soup, the dish has spread to every household and restaurant in the region, giving rise to various interpretations. Some of the most common fish used in the stew are firm white fish such as hake, monkfish, conger eel, cod, and rascasse (a type of redfish), while the usual selection of seafood includes mussels, shrimps, langoustines, baby octopus, scallops, and clams.
