Marinate this steak for 6 hours up to overnight for a tasty and tender Asian-style steak dish.
Combine Marinade ingredients in small bowl; reserve 1/4 cup marinade for basting. Place remaining Marinade in food-safe plastic bag; add beef Chuck Shoulder Steak, turn to coat. Close bag securely and marinate in refrigerator 6 hours or as long as overnight, turning occasionally.
Apricot preserves may be substituted for plum preserves.
Remove steak from Marinade; discard Marinade. Pat steak dry with paper towel. Place steak on grid over medium, ash-covered coals. Grill chuck shoulder steak, covered, 12 to 17 minutes for medium rare (145°F) to medium (160°F) doneness (top round steak 12 to 14 minutes for medium rare 145°F; do not overcook), turning occasionally and brushing with reserved marinade.
Carve steak into thin slices. Garnish with minced green onion, as desired.
