Make a white sauce with 3 tablespoons butter, melted in a skillet. Add flour and mustard and stir until smooth. Add milk and stir until thick; stir in lemon juice, parsley and onion. Fold in crab. Spoon into 6 buttered ceramic crab shells or casserole. Mix crumbs with remaining 2 tablespoons melted butter. Sprinkle over crab mixture just before cooking. Bake at 400 until hot and top is lightly browned, about 20 minutes. Canned king crabmeat can be used. This is great for a luncheon. Can be made ahead. MRS B.P.
