Sirloin roast (bone in), 4 to 10 lbs.
Sprig of rosemary
Pepper (white or black)

Leave the bone in; the marrow bastes the inside of the meat. Wipe meat, season with pepper but no salt (salt drains out juices). Put on rack in roasting pan without fat and break sprig of rosemary over top. Cook at 350 degrees for 1/2 hour, then lower heat to 300 degrees. Cook 20 minutes to the pound. Add 10 minutes if desired for well-done. Baste frequently. Serve with Yorkshire Pudding.
