Our Christmas Tradition

Place first seven ingredients and 1/4 cup broth in a large resealable plastic bag; seal bag and turn to coat. Refrigerate 4-8 hours, turning occasionally. (Best over night.)
Preheat oven to 350°
Place roast in an ungreased roasting pan, fat side up, reserving marinade. Add remaining broth to reserved marinade; pour over roast. Sprinkle roast with salt. Bake, uncovered, until a thermometer reads 145°. (1 to 1-1/4 hours.)
Remove roast from oven; tent with foil. Let stand 10 minutes before slicing. Meanwhile, skim fat from pan juices. Mix cornstarch and water until smooth; stir into juices. Bring to a boil over medium heat; cook and stir until thickened, 1-2 minutes. Serve with roast.
