1 rib eye roast, small end, approx. 4 to 6 pounds
Espresso Rub:
1 tablespoon ground espresso coffee beans
1 tablespoon packed brown sugar
1 teaspoon salt
1 teaspoon coarse grind black pepper
Balsamic Sauce:
1 cup balsamic vinegar
1/4 cup butter, at room temperature
4 teaspoons all-purpose flour
1 cup ready-to-serve beef broth
1/4 teaspoon coarse grind black pepper
Heat oven to 350 ºF. Combine rub ingredients; press evenly onto roast. Place roast, fat side up, on rack in shallow roasting pan. Insert ovenproof meat thermometer so tip is centered in thickest part of beef, not resting in fat. Do not add water or cover. Roast in oven 1-3/4 to 2 hours for medium rare; 2 to 2-1/2 hours for medium doneness.
Remove roast when thermometer registers 135 ºF for medium rare; 150 ºF for medium. Transfer roast to carving board; tent loosely with foil. Let stand 15 to 20 minutes. Skim fat from drippings; reserve drippings.
Meanwhile bring vinegar to boil in small nonreactive saucepan; cook over medium heat 20 minutes or until reduced to 1/4 cup. Mix butter and flour in small bowl until smooth. Add broth, reserved drippings and pepper to pan. Gradually whisk in butter mixture until smooth; bring to a boil. Reduce heat; simmer 1 minute, stirring constantly. Keep warm.
Carve roast into thin slices. Serve with sauce.
Serves 8 to 10.
