Preheat oven to 425 F.
First, prepare the tenderloin; the tenderloin will have one end that is smaller and thinner than the rest. Tuck 6 inches of this end under the rest of the loin. Tie the tenderloin at 3-inch intervals with kitchen string to keep its shape. Place on a rack in roasting pan.
In a small bowl, work salt and garlic together with a spoon to make a paste. Add oil, pepper, and marjoram and blend well.
Rub this paste into the beef. Place the meat thermometer in thickest section of beef.
Roast at 425 F for 40 to 50 minutes until thermometer reads a minimum of 140 F.
Remove from oven and cover beef tightly with foil. Let stand, covered with foil, for 15 minutes. The temperature will rise about 5 degrees during this time and the juices will redistribute.
Remove string and meat thermometer; then carve beef. Serve and enjoy!
