Caterers prepare and supply food and drink for events, workplaces and other occasions, either on site or from a separate kitchen. Their work may include planning menus, sourcing ingredients, cooking, packing and transporting meals, setting up serving areas and providing staff to serve guests. Some specialise in particular cuisines, dietary requirements or styles of service, such as buffets, plated meals, canaps, afternoon teas or barbecue food. Services vary according to the event and the caterer's facilities. Customers may be able to hire crockery, cutlery, glassware, tables or serving equipment, and arrange delivery, collection and clearing afterwards. Caterers may work at private functions, weddings, meetings, festivals and public venues, or provide regular meals for schools, care settings and businesses. They are expected to handle, prepare and store food in line with food safety and hygiene requirements, and food businesses must register with their local authority.
