Combine everything in a mixing bowl except the crabmeat, lobster, and panko. Taste the mixture for seasoning. Gently fold in crabmeat and lobster, careful not to break up crabmeat too much. Fold in panko, adding enough so that the mixture is not too tight.
Cook 1 crab cake and taste. Adjust the seasoning if necessary.
Form into 2 1/2-ounce cakes. Saute on both sides until golden brown.
