Oven-toast flour in a cast-iron skillet to create the base for two rich gravies without all the fat.
Preheat oven to 400°. Spread flour in a 12-inch cast-iron skillet. Bake 20 to 25 minutes or until flour is the color of pecan shells, stirring with a wooden spoon every 7 minutes. Remove from skillet, and cool completely (about 30 minutes). Refrigerate flour in an airtight container up to 2 months.
