2 lbs. roast (rump, English cut, London broil), 1 1/2-2 inches thick
1/4 c. bourbon
1/4 c. brown sugar
1 1/2 c. water
1 tbsp. lemon juice
1 tsp. Worcestershire sauce

Day before serving - In medium bowl, mix and stir all ingredients. Trim excess fat from roast and place in cake pan or Tupperware container. Pour marinade sauce over roast, and refrigerate overnight. Flip roast half-way through marinating time (total 18 hours). Barbeque over hot coals until desired degree of doneness (45 minutes to 1 hour). Brush often with left over marinade while grilling.
