The 6.5-litre capacity slow cookers are available from 25 pounds onwards. The capacity permits the cooking of large sized chicken. It is an ideal choice for large families. However, one should be careful to plan the place to put the large container. Careful handling is important owing to its weight.  The food stays warm. Cooking for a big  family at one shot is simple but it does not support cooking small portions , as the container must be half-full.
