In today's busy world it's not always easy to find the time or money to practice cooking barbecue or find the time to experiment to get the next great marinade/sauce/rub combination. So what's a guy (or gal) to do ? My solution to this problem is to use chicken breasts. They cook quickly, they're fairly inexpensive and they really have a very neutral flavor so you can taste how your marinade, rub, injection sauce all work together.
I recommend that you try each component by itself and then mix and match your marinade, rub, sauce etc... That way you really learn to understand what each component does to flavor or enhance the meat. This will also help train your taste buds for future recipe ideas.
