A salt block is a large, flat piece of salt, typically made from Himalayan pink salt or sea salt, used for cooking and serving food. These blocks can be heated or chilled, allowing them to impart a subtle salt flavor to various dishes. They are often used on the grill, in the oven, or even in the refrigerator for serving cold items. When heated, a salt block can reach high temperatures, making it suitable for searing meats, grilling vegetables, or even baking. Additionally, they can be used as a unique serving platter for appetizers, enhancing the presentation and taste of the food served on them.
