Bacalao al pil pil is a signature dish of Spain; we have verified places to eat it in Bilbao and San Sebastián.
Bacalao al pil pil is a Bilbao invention: salt cod slow-cooked in olive oil with garlic and dried chili, then emulsified by shaking the pan until the gelatin and oil form a thick yellow sauce that coats each piece.
Bacalao al pil pil traces to mid-19th-century Bilbao, when merchant Simon Gurtubay over-ordered salt cod from Norway in 1836. Forced to sell the surplus, Bilbao kitchens developed the slow-emulsified sauce technique that made the dish a city staple. The pil pil name imitates the bubbling sound of the slow simmer. Casa Rufo, La Despensa de Etxanobe and Mina all run versions; the deep-yellow emulsion is the test, as the gelatin from the cod skin must bind with the oil into a thick sauce without breaking.

Bacalao al pil pil is salt cod slowly cooked in olive oil with garlic until the gelatin from the skin emulsifies the oil into a creamy pale-yellow sauce, served in the earthenware cazuela it was cooked.
Bacalao al pil pil grew out of the Basque salt cod trade, which had Basque boats fishing the Newfoundland banks from the 16th century and Bilbao as the main Spanish port for the product. Bilbao legend dates the dish to 1836, when a merchant named Simon Gurtubay is said to have over-ordered salt cod just before the Carlist siege and the city cooked its way through the surplus with the garlic and oil still to hand; historians treat the story as folklore, since no shipping record supports it. The pil pil emulsion technique (the gentle shaking of the cazuela to bind the cod gelatin with garlic-infused oil) developed in Basque kitchens through the 19th century and remains the canonical preparation for salt cod across the Basque Country. Casa Vergara in San Sebastian's Old Town serves it as a pintxo; Bodegon Alejandro serves the full plate.
