A chef hat, also known as a toque, is a tall, pleated hat worn by professional chefs. Traditionally white, it symbolizes the chef's expertise and professionalism in the kitchen. The height of the hat can indicate the chef's rank, with taller hats representing higher positions, such as a head chef. The design of the chef hat helps to keep hair away from food and maintain hygiene. It is often made from cotton or a similar fabric, allowing for breathability in hot kitchen environments. The pleats in the hat can also represent the number of recipes or techniques a chef has mastered.
