Step #1 Mix 10 c water, sugar & salt In a large-ish roasting pan or stock pot.
Step #2 Place chicken skin side down in the water mixture (add more water if necessary to cover chicken.
Step #3 ).
Step #4 Cover up & put in the fridge overnight.
Step #5 Preheat oven to 300F degrees.
Step #6 Drain chicken & pat dry.
Step #7 Place chicken halves skin side down in a single layer on heavy large baking sheet with rim, that has been lined with aluminum foil wrap, preferably Release foil wrap.
Step #8 Brush each half with 2 tbsps barbecue sauce.
Step #9 Sprinkle top with 1-1/4 tsp of Rub.
Step #10 Turn halves over & repeat.
Step #11 Bake chicken skin sides up, basting every 20 mins (VERY IMPORTANT) with pan juices, for about 2 hrs.
Step #12 THIS IS WORTH THE EFFORT!
If you use chicken parts, thigh or drumsticks, reduce the cooking time to 1 hr, like breast, 30 mins-ish.
Step #13 And reduce cooking time even more if using a convection oven.
