• Place 5 ounces of the shrimp In the food processor. Pulse shrimp a few times until finely chopped but not puréed. Roughly chop the remaining shrimp into ⅓ inch pieces.
• Transfer to a large bowl and add the cod, 1/4 cup of the scallions, the dill, salt, and pepper. Mix until well blended.
• Refrigerate the mixture for 4 hours.
• Meanwhile, in a small bowl, combine the mayonnaise, Old Bay, and the remaining two tablespoons of scallions; mix well and refrigerate.
• Heat a grill to medium and oil the grates.
• Moisten your hands with water, then form the mixture into four ½-inch-thick patties. Coat the patties lightly with oil on both sides and place on a parchment liked baking sheet until ready to grill.
• When the grill is cleaned, oiled, and heated, place the burgers on the grates and cook until lightly charred and cooked through, 4 to 5 minutes per side. Do not overcook – a thermometer inserted in the center of the burger should read 145 °F. They will continue to cook as they rest.

  Please ensure the first side is firm before flipping, as you want the heat to bind the seafood.

• Remove from the grill and let rest.

Assembly

• Grill buns if desired. Place the bottom of the bun on a plate, add a layer of crispy lettuce, and top with a seafood burger. Squeeze lemon on the burger patty. Place a large dollop of the Old Bay mayonnaise on the burger, then layer on the pickles, radish slices, and other lettuce as desired. Cover with the bun top, and enjoy!
