Cheese is a solid food made by coagulating milk, usually through bacterial culture and rennet enzymes. Cheesemaking dates back thousands of years and involves processes like curdling, pressing, salting, and aging the curds. There are hundreds of varieties of cheese from around the world, categorized by factors like milk source, texture, aging process, and the addition of molds or bacteria. When serving cheese, it is presented on a board with a variety of styles, accompanied by crackers, bread, mustards, and fruits or vegetables.
