Season to taste. Add salt and pepper and/or a splash of cream, wine or vinegar. Taste as you go. Serve as is for a rustic version but strain if you want a silky smooth sauce.
Pan Jus: Just heat to simmer and stir occasionally with the lid off until the liquid reduces to desired thickness.
Classic Gravy: Combine stir together equal amounts of flour & soft butter, OR cornstarch & cold water, making smooth mixtures. Gradually stir bits of the mixtures into simmering sauce; bring to boil, stirring until thickened (Note: 1 tbsp/15 mL cornstarch or flour thickens 2 cups/500 mL liquid.).
