  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
   2      cans          Dr Pepper
     1/4  teaspoon      Lawry's seasoning salt
                        restaurant style ground pepper
   2                    beef bouillon cubes -- dissolved in water
   4      cloves        minced garlic
                        Worcestershire sauce
   1      tablespoon    lemon or lime juice
   1      bottle        barbecue sauce
     1/4  teaspoon      meat tenderizer

Preparation:

Mix all together well, marinade brisket in large roaster type pan overnight or better yet, for two(2) days. Smoke to your own desire. I Q for about 10-14 hours on my New Braunfels Black Diamond and then for about 12 more hours in the oven(covered) at 150-175 F. Cuts like butter when ready.
