Cooking hats, often known as chef hats or toques, are tall, pleated hats traditionally worn by chefs in professional kitchens. They are designed to signify the chef's rank and expertise, with the number of pleats sometimes representing the number of recipes or techniques mastered. The height of the hat also serves a practical purpose, helping to keep the chef cool while cooking. These hats are typically made from cotton or a similar fabric, allowing for breathability and comfort. In addition to their symbolic meaning, cooking hats help maintain hygiene by keeping hair away from food. They are an essential part of a chef's uniform, promoting professionalism in the culinary arts.
