How to Thicken Pan Gravy
If a thicker pan gravy is desired, mix 1/4 cup water with 2 to 3 Tbsp. flour. Transfer meat and vegetables from pan to platter; cover to keep warm. Bring reserved liquid in pan to boil on medium-high heat. Gradually whisk in flour mixture; cook and stir until thickened to desired consistency.
Prepare using a 2-lb. beef rump roast and increasing the final cooking time to 2 to 2-1/2 hours or until meat is tender.
Prepare using any other all-purpose potato. If only baking potatoes are available, add them to cooking liquid the last hour of the cooking time.
