Himalayan salt slabs are also sometimes called salt blocks, platters or plates. It is use for cooking, chilling and curing or as a decorative serving platter. Salt slabs can even be used for bathing. Once heated properly, salt slabs tend to hold the same temperature for a long time (the exact length of time it will stay hot depends on the temperature). When food is place on the salt slab, the slab will impart mild saltiness and mineral flavoring to it.
