Make a gravy using the drippings from the pot. To do so, melt 2 tablespoons of butter in a skillet over medium heat. Whisk in 2 tablespoons of flour and cook for 30 seconds, stirring constantly. While continually whisking, gradually add 1 - 1 ½ cups of strained juices/drippings from the pot until the gravy reaches the desired consistency. Continue whisking while the gravy bubbles and cooks for 1-2 minutes. Season with additional salt and pepper, to taste.
