If your gravy is too runny and thin, mix equal parts flour and cornstarch together and sprinkle it into gravy to thicken it. Sprinkle it in a little at a time and stir, it should thicken up in no time.
To thicken gravy, I use instant mashed potato flakes. Works real well.
I do it Cathy's way, but I would like to add that I take the gravy off and let it clam down (not boiling). Then put a little in, and bring it to a boil to check thickness. Also I make a Rue (butter and flour), that can be added to boiling gravy and I put the rest in the freezer till next time.
To quickly and easily prepare flour or cornstarch thickening, just put about 1 inch of water in small jar, add flour, add more water, then shake vigorously. The thickening is quickly ready, and without lumps.
