Slow Cooker Barbecued Ribs This is a great recipe!!!!!!!! i didnt have any cola but i did substitute a bottle of dark beer.. I think it turned out amazing. I also used Jack Daniels BBQ sauce. The bones literally cleaned them self. The meat gets so tender. I cooked mine for about ten hours. I also didnt throw away the juice from the main cooking i used that and mixed it withbq my bBQ sauce it was delicous
