Place pork ribs in a slow cooker with salt, pepper and a can of cola, and cook them on high for four hours or low for seven hours. After the ribs have cooked, drain the liquid, and add a bottle of barbecue sauce if desired.
Rub the pork ribs with 1 teaspoon of salt and 1/2 teaspoon of pepper. Place the ribs in a slow cooker with 1 can of cola, and cook them on low for seven hours or high for four hours. Drain the cola from the slow cooker, and add one bottle of barbecue sauce, if desired, to the ribs, covering them. Cook the ribs on high for another hour before serving.
To use another recipe for cooking ribs in a slow cooker, brown them in a 400 degrees Fahrenheit oven for 15 minutes per side. Then, place the ribs in the slow cooker. In a separate bowl, mix together 2 cups ketchup, 1 cup chili sauce, 1/2 cup brown sugar, 4 tablespoons apple cider vinegar, 2 teaspoons oregano and 2 teaspoons Worcestershire sauce. Pour the sauce over the ribs in the slow cooker. Cook the ribs on low for six to eight hours or until they are tender.
