Timetable for roasting is 15 min per rib, or 5 min per pound. For example
a 3 rib roast, weighing 8-9 pounds, will roast for 40-45 min.
Bring the Roast bring to room temperature. Preheat oven to 500º. Place the roast in a shallow roasting pan. Sprinkle with a little flour and rub the flour lightly into the fat. Season generously with salt and pepper. Place a tent of foil loosely over the top of the meat to prevent spattering.
When the cooking ends, turn off the oven, do not open oven door. Allow the roast to remain in the oven for at least 1 hour or until the oven is lukewarm, about 2 hours. The Roast will be rare on the inside and crunchy on the outside.
