Step-by-step

  • Prepare the tartar sauce by combining all of its ingredients (except salt and pepper) in a small bowl. Taste and season with salt and pepper. Refrigerate until ready to use.
  • Scale (if needed) and rinse the fish, then pat dry with paper towels. Do not remove the skin. Cut the large fillets into sandwich-size pieces. Make two scores in the skin with a sharp knife to prevent curling. Do not make too many scores to avoid drying out the flesh during cooking. For best results, pick the thicker pieces as they will allow for a beautifully browned exterior while maintaining soft and flaky interior. The thinner, leftover pieces can be used for other dishes.
  • Season the fish fillets with salt and pepper on both sides and set aside.
  • Heat one tablespoon of butter and one tablespoon of oil in a large frying pan over medium-high heat. Add one more tablespoon of oil if the bottom of the pan is not fully covered. Add the fish, skin side down and fry for about 3-5 minutes, depending on thickness, until nicely browned. Flip and continue frying for another 3-5 minutes on the other side. In my case it took me 4 minutes per side to achieve perfect doneness.
  • Check the fish for doneness and remove it from the pan as soon as it's just done. Depending on the size of the fillet pieces and you the size of you pan, you may have to do the frying in two batches. You may need to add more oil for the second batch.
  • Assemble the sandwiches and enjoy. I like spreading some tartar sauce on the bottom half of the bun, then pour some on top of the fish.
The ingredient list omits the physical mechanics required to turn raw seafood into a stable, structural sandwich element. Selecting fillets that measure at least one inch thick ensures the interior retains moisture while the exterior develops a crust. Thinner cuts overcook instantly in high heat.

Controlling Heat and Moisture

Patting fish dry with paper towels is mandatory. Surface moisture prevents the proteins from making direct contact with the pan, blocking proper browning. Scoring the skin precisely twice prevents the fillet from cupping and lifting away from the hot surface. Combine butter and vegetable oil in a heavy skillet. Butter delivers rich flavor, but the neutral oil raises the smoke point so the milk solids do not burn during the 4 to 5 minutes per side required for medium-high frying. Maintain medium-high heat throughout this window.

Balancing the Condiments

Fatty fish demands high acidity to balance the palate. Lemon juice added to mayonnaise cuts the richness. Chill the sauce for at least 30 minutes before assembly to let the chopped dill pickles, shallots, and herbs hydrate and meld.
