How much liquid do I add?

Water or liquid is necessary to create steam. When cooking meat or poultry, the water or liquid level should cover the ingredients to ensure effective heat transfer throughout the crock. Some manufacturers of slow cookers recommend adding liquid to fill the stoneware 1/2 to 3/4 full. Follow the manufacturer's recipes and directions for best results.
