2 bottles of barbecue sauce, whatever you like
1-1/2 cups Dr. Pepper or Cola, again whatever you like
2 tablespoons liquid smoke
2 tablespoons Worcestershire sauce
Mix it all up in your slow cooker and add some meat! I use either 10 pounds of country style pork ribs OR 6 pounds of ribs and 4 pounds of chicken.
If you're using just ribs, cook 10 hours on low.
If you're using ribs and chicken, cook ribs for 4-5 hours, then add your chicken and cook for another 5-6 hours, for a total of 10 hours on low.
You can spice up the sauce any way you like. I've added green pepper and onion in the past, garlic is always good :) grill or cajun spices work well also. Enjoy!
