A personal chef is a chef who is hired by different clients and prepares meals in the clients' home kitchens, based on their needs and preferences. In most cases the chef leaves the meals he had cooked packaged in containers and refrigerated or frozen for the client to enjoy later. Some personal chefs focus on preparing dinner parties and other special events, which means they are responsible for shopping, preparing the meal, serving the guests and cleaning up afterward. The menu is preplanned and discussed with the client, then prepared in their home. According to health-department guidelines, all food must either be prepared in the home of the client or in a kitchen that has passed an official health inspection.
