Recommended temperatures for beef are: Rare 60C; medium 70C; well done 80C. Baste the meat with the juices at least three times during cooking. When it's done, take out the meat and leave it to rest for at least 20 minutes.
Place a meat thermometer in the center of your steak; a medium-rare steak should have an internal temperature of 130 to 135 degrees F. Alternatively, use a finger to press down on the steak; a medium rare will be slightly bouncy but not soft or firm to the touch.
