Make the gravy by adding the 2 tablespoons remaining flour to the pan drippings, scraping the bottom with a wooden spoon. Stir in the remaining 1/4 teaspoon pepper, and the salt. Reduce the heat to medium and cook, stirring frequently, until the flour is medium brown and the mixture is bubbly. Slowly add the whole milk and the Ac'cent, if using stirring constantly. Return the steaks to the skillet and bring to a boil over medium-high heat. Reduce the heat to low, and place the onions on top of the steaks. Cover the pan, and let simmer for 30 minutes.
