Instructions
Mix all ingredients in a large bowl and blend well. In a gallon-size ziplock plastic bag, combine all ingredients, add trip-tip and seal bag. Refrigerate overnight.
Heat gas grill to 400 degrees. Remove tri-tip from marinade and lay on the hot grill; discard remaining marinade. Cook for 5 minutes. Turn over and grill for another 7 minutes. Turn occasionally and continue cooking until internal temperature reaches 130 degrees.
Allow to rest 10-15 minutes, then cut across the grain into thin slanting slices.
Notes
The sugar content of the marinade will make for a dark crust.
