Preparing delicious meals may be the most obvious part of the work of a professional chef, but the job requires much more. Chefs must prepare budgets, calculate profit margins, control and order stock, and keep up with the latest food trends such as organic and vegetarian cuisine and healthy eating regimes. Communicating well with a team is also part of the high-pressure environment in a successful kitchen, while good hygiene is essential for the health and safety of customers and fellow workers.
