COOK fat drippings and broth in a roasting pan or saucepan over medium heat, until hot.
STIR corn starch and water in a small bowl until smooth; add to pan. If desired, add a dash of poultry seasoning for chicken and turkey gravies, a sprinkle of thyme for beef or a pinch of rosemary for pork. Stirring constantly with a wire whisk, bring to a boil over medium heat and boil 1 minute. Season with salt and pepper.
Microwave directions: Combine all ingredients in a 2-quart, microwave-safe bowl. With a whisk, stir until corn starch is completely dissolved. Microwave on HIGH (100%) for 7 to 9 minutes or until mixture boils, stirring every minute. Boil for 1 minute. Season with salt and pepper.
