Because Himalayan Salt Blocks generally have an extremely low amount of porosity, and virtually no residual moisture (.026%), the salt plates can be safely heated or chilled to great extremes. We have tested them from 0°F up to 700°F (-18°C to 370°C). Salt melts at 1473.4°F (800.8°C).
Two other considerations come into play when working with our Himalayan salt blocks. First, their lack of porosity means that the surface area touching your food is minimal, so these large blocks of salt will impart only a very moderate saltiness. Second, the high quantity of trace minerals (1.2% sulfur, .4% calcium, .35% potassium, .16% magnesium, and 80 other trace minerals) impart a more mild and full taste to the salt, and by extension, more flavor complexity to your food.
Cooking with Himalayan salt Blocks, plates and bowls is the latest trend on the culinary scene. These cooking slabs can be used to grill, broil, or heat foods on the stove top, as well as serve chilled foods such as cheeses, fruits, and sushi.
