"Old-fashioned white gravy that uses mainly household items and goes great with biscuits, salmon patties, mashed or other potatoes, eggs, fried bologna or sausage, or your choice of good Southern food. Gravy will thicken further as it cools. Whisk in additional milk to thin as desired."
Combine 3/4 cup milk, flour, beef bouillon, salt, and pepper in a container with a lid. Cover and shake until well mixed.
Heat oil in a skillet over medium heat. Pour in flour mixture carefully; whisk until smooth. Whisk in the remaining 3/4 cup milk. Cook, whisking constantly, until thickened and bubbly, 8 to 10 minutes.
