Old Bay Burger

Grind or finely chop fish using the small die in a stand mixer's meat-grinder attachment, a food processor or a knife.

In a large bowl, stir together the panko, parsley, egg white, Old Bay, crushed red pepper and mustard. Stir in the fish. Form into 8 patties, about 3/4-inch thick.

In a large skillet, heat 1 tablespoon of the butter over medium heat. Add 4 patties. Cook for 8 to 10 minutes or until cooked through (160°), turning once. Repeat with remaining butter and burgers. Serve on buns with desired toppers.
