Never Use Himalayan Salt bricks for cooking. As most of them are not crafted from 100% Edible Himalayan Salt. As Himalayan Salt has different grades and also have food grade which most of the people dont know. Always use Himalayan Salt Cooking plates which are expensive and are healthy just as salt with minimum amount of sand & clay in it. Heat your Himalayan salt block to high temperatures and sear thinly sliced meats, fish, vegetables, seafood, and other quick-cooking foods. Or, chill it for use in serving sushi, appetizers, cold meats and cheeses, fresh fruit and vegetables, and even cold desserts.
