To protect the undercut (tenderloin) of the roast from cooking too quickly or drying out arrange fat bacon slices or sliced fresh pork fat over this section and tie in place with twine.
Arrange roast fat side up in a shallow roast pan and spread lean surfaces with a mixture of mustard and Worcestershire sauce.
Sprinkle with garlic powder and roast at 325F (160C) about 1 1/2 to 1 3/4 hours for rare, internal temperature 140F (70C); 2 to 2 1/2 hours for medium, 160F (75C); 2 1/2 to 2 3/4 hours for well done, 170F (80C).
Keep warm for 20 minutes or so before carving.
Scrape meat drippings into a small skillet and skim off the fat.
Measure drippings and add half as much bouillon.
Simmer until slightly reduced in quantity.
Taste and season if necessary.
Just before serving, add the juices collected in the meat platter; pour into a warm sauce boat.
