Decazeville and the Lot valley, Aveyron — the landlocked Aveyron preparation of dried air-cured cod (stockfish, not salt-cured) with walnut oil, potato, and hard-boiled egg, brought inland via the Lot river trade route from the Bay of Biscay. The dried cod was carried by barge from Bordeaux to Entraygues-sur-Truyère and then by mule track to the mining towns of the Bassin de Decazeville. The Portuguese and Basque Atlantic salt cod trade — the Portuguese bacalhau tradition and the Basque-Breton dried cod fleet operating off Newfoundland and Norway — supplied the dried fish that arrived in Bordeaux as bacalao and klipfish, then moved inland to become the Aveyron's emblematic fish preparation, despite the region having no coastline. · Seafood
The walnut oil carries nutty, slightly bitter, and deeply aromatic notes that no olive oil can replicate in this context. Garlic paste and parsley provide a sharp green counter to the rich fish-and-walnut combination. The potato's starch absorbs the walnut oil and becomes a vehicle for the flavour. The hard-boiled egg adds richness and a protein counterpoint. This is a dish of extraordinary individuality — it tastes of nowhere but the Lot valley.
Salt cod (morue) substituted for stockfish, olive oil substituted for walnut oil.
Gadus morhua (Atlantic cod) as stockfish — air-dried without salt, traditionally from Norwegian klipfish producers or Portuguese bacalhau sources. The distinction between stockfish (stokkfisk — unsalted, air-dried) and salt cod (morue, bacalà, bacalhau — salt-cured before drying) is absolute: estofinado uses only stockfish. Solanum tuberosum waxy variety — Charlotte, Nicola, or La Ratte (the Aveyron variety); floury potatoes collapse under the walnut oil instead of holding form. Juglans regia cold-pressed walnut oil — specifically from the Périgord or Lot valleys (AOP Noix du Périgord preferred); heated or old walnut oil becomes rancid and ruins the preparation.
