Directions

Seafood burgers

1. Preheat the oven to 350°F (180°C).
2. Chop the scallops and prawns into small chunks.
3. Place cold halibut in a food processor and pulse until fish is well chopped and pulpy.  Do not over process. Transfer to the bowl of scallops and prawns. Add green onion, parsley, dill, lemon juice, lemon zest and lightly season with salt and pepper.
4. Separate eggs.  Add yolks to the seafood and herbs.  Whisk egg whites to stiff peaks and fold into the seafood mixture. Add panko, red chilli, and stir together gently. Flatten mixture in the bowl with a spatula and press it gently into the bowl. Cover with plastic wrap and place in refrigerator for 30 minutes to bind.
5. Use a 4-inch mold to form seafood mixture into patties.  Sprinkle a layer of panko over a flat surface, place mold on the panko and fill it with the seafood. Flatten the seafood into a thick burger. Sprinkle with a more panko overtop.
6. Add butter and oil to a hot pan. Lay patties in the pan, panko-covered side down. Cook for 1-2 minutes a side, until outer layer is crispy. Remove patties to a parchment lined baking sheet. Place in oven for 5 minutes.
7. Drizzle burger buns with oil and place in oven with the burgers.
8. In a bowl, combine shallot, garlic, parsley, capers, lemon juice, mayonnaise, sour cream, and horseradish sauce. Season with salt and pepper. Stir to combine.
9. Spoon tartar sauce over each bun. Add seafood patty, and more tartar sauce. Finish burger with iceberg lettuce, tomatoes, salt, pepper, onion, and a pickle, or your own favourite toppings.
