Combine the water, ketchup, brown sugar, vinegar, Worcestershire sauce, butter, lemon juice, mustard, chili powder, and paprika in a 2-quart saucepan. Cook, over medium heat, until the mixture comes to a boil, then remove from the heat. Combine the flour, salt and pepper in a large oven-browning bag. Add the chicken and shake to coat well. Place in a shallow roasting pan. Open the bag and pour the sauce over the chicken. Secure the bag loosely with a twist tie and pierce the top of the bag 6 times with a sharp knife. Bake in a preheated 350 Degree F. oven for 1 hour or until tender.

To Serve:

Remove the chicken from the bag. Pour the sauce into a bowl and ladle off the excess fat. Serve the chicken with the sauce on the side.
