Mix 1/2 cup flour, 1/2 teaspoon salt and pepper. Dredge tenderloins in the flour mixture. In a large skillet heat the oil over medium heat. Fry the tenderloin until brown on both sides. Remove from oil and place in a baking dish. ( lightly greased)
Pour oil out of the skillet leaving 4 tablespoons and the brown bits left from frying the tenderloin. Add 1/2 cup flour plus the flour left over from coating the tenderloin for frying. Whisk in 1 teaspoon salt and stir constantly until flour browns, slowly whisk in liquids ( water and milk) and cook about 2 minutes. Gravy will be very thin, pour over the meat in baking dish, cover tightly with foil and bake in 325 degree oven for 2 hours. Gravy will thicken during baking. Serve with biscuits or rice.
This is a great breakfast, brunch, lunch, or dinner recipe.
