This iconic Basque tapa transforms humble salt cod into a silky, glossy masterpiece through the magical emulsification of olive oil and the natural gelatin from the fish skin. Served piping hot in a clay dish, the luscious sauce is meant to be soaked up with crusty bread.

Ingredients
For the Cod and Sauce
- 1.5 lbs (700 g) skin-on salt cod (bacalao), soaked
- 1.5 cups (360 ml) good-quality extra virgin olive oil
- 6 garlic cloves, thinly sliced
- 2 dried guindilla or ñora peppers, stems removed
- 1 small slice day-old white bread, crust removed (optional)
- 2 tablespoons fresh flat-leaf parsley, finely chopped
- Pinch of flaky sea salt, only if needed
Directions
- Desalt the cod by submerging it in cold water for 24 to 48 hours, changing the water every 8 hours. Pat dry with paper towels, remove any bones, and reserve the skin.
- In a wide, low-sided earthenware or stainless pan, combine the olive oil, sliced garlic, and dried peppers. Warm over very low heat for 8 to 10 minutes until the garlic turns pale gold and fragrant—do not let it brown.
- Lift out the garlic and peppers with a slotted spoon and set aside. Increase the heat just slightly and gently lower the cod pieces, skin-side down, into the warm oil.
- Cook the cod at a bare simmer (around 160°F / 70°C) for 10 to 12 minutes, spooning oil over the top, until the flesh flakes easily and releases its natural gelatin into the oil.
- Transfer the cooked cod to a warm serving dish and cover loosely. Strain the infused oil through a fine sieve into a clean pan and return it to very low heat.
- Add the bread slice (or 1 tablespoon cold water) to the warm oil. Holding the handle with one hand and a folded towel over the lid with the other, shake the pan vigorously back and forth for 1 to 2 minutes until the oil turns pale, thick, and creamy.
- Discard the bread. Slide the cod back into the pan with the emulsified oil, scatter the reserved garlic and peppers over the top, and warm through for 30 seconds.
- Taste and adjust salt only if needed. Spoon into warm cazuelas or shallow bowls, drizzle with extra emulsified oil, and finish with chopped parsley.
Cook’s Notes
- Plan ahead: salt cod needs 24–48 hours of soaking in cold water, changed every 8 hours, before cooking.
- Keep the oil at a bare simmer—never let it boil or the emulsion will break and the cod will turn rubbery.
- The natural gelatin from the cod skin is what thickens the sauce, so don't trim it away before cooking.
- If the sauce refuses to thicken, add a small ice cube or splash of cold water to shock the emulsion into setting.
- Serve with thick slices of toasted sourdough or a rustic baguette to soak up every drop of the silky oil.
