A pepper mill is a kitchen tool used to grind whole peppercorns into fresh pepper. It typically consists of a cylindrical body, a grinding mechanism, and a top or bottom that can be twisted or turned to release the ground pepper. The grinding mechanism can be made of metal or ceramic, allowing for different levels of coarseness. Pepper mills come in various sizes and designs, often made from materials like wood, stainless steel, or acrylic. They are commonly used in cooking and at the dining table to enhance the flavor of dishes. Freshly ground pepper is known for its stronger aroma and taste compared to pre-ground pepper.
