Preheat oven to 375°.
Trim fat from pork; score a diamond pattern on top of pork. Combine the honey and the next 4 ingredients (honey through red pepper) in a small bowl. Combine 2 tablespoons honey mixture and onion wedges; toss well to combine. Place the pork on the rack of a broiler pan or roasting pan. Arrange onion wedges around pork. Brush the remaining honey mixture over pork. Insert a meat thermometer into thickest part of pork. Bake at 375° for 1 hour and 15 minutes or until thermometer registers 155° (slightly pink). Place pork on a platter, and cover with foil. Let stand 10 minutes for the pork to reabsorb juices. (Temperature of the roast will increase 5° upon standing).
Remove rack from pan. Add 1/2 cup broth to drippings in pan, scraping pan to loosen browned bits. Combine drippings mixture and 1/2 cup broth in a small saucepan. Bring to a boil; reduce heat, and simmer 5 minutes. Cut pork diagonally across grain into thin slices; serve with onions and sauce.
