I use a cooking bag like the ones used to bake a turkey. The day before you are going to serve it bake at 350 approx. 3 hrs, let cool, then slice into a 9x13 baking dish, I sparingly pour BBQ sauce on the layers. Cover with foil and ref. about 45 mins before serving, heat in a350 oven for about 30 minutes. I get rave reviews on mine. Hope this helps
