How to Make It
Heat broiler. In a medium bowl, finely crush the potato chips. Add the crabmeat, tartar sauce, mustard, and ¼ teaspoon pepper. Stir to combine.
Form the mixture into 8 patties and place on a parchment- or foil-lined baking sheet. Top each with a pat of butter.
Broil the patties until browned, 1 to 2 minutes. Serve with the lemon wedges.
