In a saucepan, heat the turkey or chicken drippings and chicken broth over medium heat.
In a small bowl, whisk together the flour and water until smooth.
Gradually whisk the flour mixture into the saucepan, stirring constantly, until the gravy thickens.
Season with salt and pepper to taste.
Simmer for about 5 minutes, stirring occasionally, until the flavors meld together.
Serve hot with your favorite meal.
