Very small prime rib roast
My mother would cook a rib roast for our family of four maybe once a year because it was so expensive. I didn't pay much attention to how she cooked it. I think she put it on a rack and cooked it uncovered in the oven. I live alone and want to treat myself to a rib roast and I think the smallest available in my supermarket is 2-3 ribs. How can I cook it to medium rare withour drying it out?
