1/4 cup fresh lemon juice (1 to 2 lemons)

Steps:

Process half of the shrimp in a food processor until a paste forms. Add the cod, remaining shrimp, and the bread crumbs, capers, scallions, parsley, lemon juice, salt, and pepper. Pulse until just combined (do not overprocess).
Using dampened hands, shape into 4 patties. Refrigerate, covered, until cold and firm, about 1 1/2 hours (or overnight).
Preheat the grill to medium-high (if using a charcoal grill, coals are ready when you can hold your hand above grill for just 3 to 4 seconds). Brush the grill and the burgers with oil. Grill, flipping once, until cooked through, about 3 minutes per side. Toast the buns on the grill during the last minute of cooking, if desired. Serve the burgers on the buns; top with lettuce. Serve with tartar sauce, if desired, and the lemon wedges.
Tarragon Tartar Sauce
Stir together the mayonnaise, relish, lemon juice, capers, tarragon, salt, and pepper in a medium bowl. The sauce can be refrigerated in an airtight container up to 1 week.
