A chef is a professional cook who is skilled in preparing and presenting food. Chefs often work in restaurants, hotels, or catering services, and they may specialize in various cuisines, such as Italian, French, or Asian. Their responsibilities include creating menus, managing kitchen staff, and ensuring food safety standards are met. Chefs typically undergo formal training at culinary schools or through apprenticeships. They must possess a strong understanding of cooking techniques, flavor combinations, and presentation skills. Many chefs also have experience in different kitchen roles, such as line cook or pastry chef, before advancing to their current position.
