This was one of my favorites as I grew up, as the delicious BBQ smell would fill our little house as it baked in the oven. We didn't eat a lot of barbecued things in the winter, since we lived in Minnesota, and this was a nice surprise.
Brown meat at 400° in a 9x13 pan.
Mix remaining ingredients and pour over meat.
At 300°, bake covered for 2-3 hours until meat is tender.
