Ingredients
Directions
Set the pan with drippings over boiling water.
Scrape browned flour from the sides and bottom of the pan toward the center.
Add a little more flour as you stir.
If the water has boiled away, add boiling water from the teakettle.
Stir until the gravy is the consistency of rich cream.
Season with pepper and pour into a gravy boat.
