Natural Himalayan Salt Plank - Rectangle 4x8x2, Himalayan Kitchen Salt Planks are beautiful slabs of pure Himalayan Pink Salt, hand cut from the Himalayan Mountains. Heat in the oven or on the grill to sear food and they add an enhanced salt and mineral flavor. Their density helps distribute heat more evenly. Or chill in the refrigerator and they make a perfect tray for serving cold food. The possibilities are endless. They are naturally anti-microbial, so clean up is quick and easy. A quick scrub or rinse will do the trick. (Heating them will change their appearance over time.)
