A salt mill is a kitchen tool used to grind salt into finer particles for seasoning food. It typically consists of a container that holds salt and a grinding mechanism, often made of ceramic or stainless steel. Users can adjust the coarseness of the salt by turning a knob or adjusting a screw, allowing for versatility in cooking and presentation. Salt mills come in various designs and sizes, making them suitable for different kitchen styles. They are often paired with pepper mills, which serve a similar purpose for grinding peppercorns. Both tools enhance the flavor of dishes and are common in many households and restaurants.
