Combine remaining ingredients with a whisk in a seperate bowl, reserving 3/4 c for serving and dump the rest into the baggie or dish with the ribs. Cover and chill 8 hours or overnight, turning occasionally.
Place ribs in a pan and cover with foil; bake for 3 hrs at 275degrees and DO NOT peek!
Finally, you can either grill for 10 min on each side at medium heat on an open grill or broil for about 5 minutes on each side to brown the ribs.
Warm the reserved 3/4 c marinade and serve on the side.
