Step 1Heat the oven to 425 degrees.
Step 2Combine the crab meat, mayonnaise, Dijon mustard, whole-grain mustard, carrot, lime juice, green onions, potato, cilantro, soy sauce and bread crumbs. Form into patties about 3 inches in diameter.
Step 3Heat the oil in a skillet over medium heat and cook half the patties until they're golden brown on one side, 4 to 5 minutes. Remove them to a baking sheet. Cook the remaining patties and add them to the baking sheet.
Step 4Bake the crab cakes until they're heated through, about 3 minutes. Serve with Mustard Sauce.
Step 1Cook the garlic and shallots in the butter over medium heat until softened, about 2 minutes. Add the wine and clam juice and continue cooking until the liquid is reduced by half, about 10 minutes. Add the cream and continue to cook until the sauce is again reduced by half, 10 minutes. Add the Dijon mustard and lemon juice. Cook for 1 minute and strain. Stir in the whole-grain mustard and serve. Makes about 3/4 cup.
