Brown Gravy

1. Melt the butter in a saucepan over medium heat. Sprinkle the flour over the butter and cook, stirring constantly, until the mixture turns golden brown, about 8 minutes. 2. Pour the beef stock, the chicken stock, and the rest of the ingredients into the flour mixture, whisking to combine. Bring the mixture to a boil, whisking frequently. Reduce the heat and simmer the gravy until it thickens and reduces slightly, about 15 minutes. 3. Taste for seasoning, adding more salt and pepper, if needed.
