Directions
Prepare the beef tips by removing any silver skin that may be attached. Set aside.
In a 2 cup measuring cup combine the soy sauce, oil, molasses, ginger, dry mustard, minced garlic. Mix well.
Place the beef tips in a glass or ceramic pan. Pour the marinade over the beef. Cover and refrigerate for a minimum of one hour, or up to overnight. You'll want to turn the meat periodically to make sure the marinade is absorbed by all sides of the meat.
Cook on a hot grill until desired level of doneness.
