Pour 2 cups water into pan with drippings. Add salt and pepper to taste and bring to full boil.
Combine flour and 1 cup cold water and mix thoroughly, making sure there are no lumps in the mixture.
Using a whisk, begin to pour flour mixture into boiling liquids, stirring constantly and briskly. Continue until thick but not lumpy. Enjoy!
PS: If gravy gets lumpy, pour gravy through sieve into your gravy boat.
