Basic Gravy Recipe

In a frying pan over medium heat, heat oil. (If desired, use the same oil used to fry your dish for more flavor.) Add flour and stir to coat. Cook until the flour no longer smells like flour. 

Using a whisk, gradually pour in the stock. (For better flavor, use the drippings from your dish.) Whisk until the flour mixture is incorporated. Bring to a simmer and cook the gravy until thickened, whisking until the mixture has no lumps. Season to taste with salt and ground black pepper. Serve while hot.
