Mill Creek Crab Cakes

Name: Mill Creek Crab Cakes
Ingredients: 1 pound jumbo lump or backfin blue crabmeat, preferably from Maryland (or “Maryland-style,” which I’m guessing is code for North Carolina); 1 large egg; 1/4 cup panko or fresh breadcrumbs; 2 tablespoons mayonnaise, homemade is best but Hellman’s will do in a pinch; 1 tablespoon fresh flat-leaf parsley, chopped; 1 teaspoon Old Bay seasoning, more or less to taste; 1 teaspoon dry mustard; pinch sea salt; 1 tablespoon unsalted butter; 1 tablespoon canola oil; lemon wedges for serving
