The Sunday roast is a traditional British and Irish main meal served on Sundays (usually in the early afternoon), and consisting of roasted meat together with accompaniments. It is popular throughout Great Britain and Ireland. Other names for this meal are Sunday dinner, Sunday lunch, Sunday Tea, Roast dinner, and Sunday joint. The traditional Sunday roast has been traced back to Yorkshire, England during the Industrial Revolution. It is believed this tradition arose because the meat could be left in the oven to cook before church on a Sunday morning, and it would be ready when the family arrived home at lunchtime. The meal is often comparable to a less grand version of a traditional Christmas dinner in these cultures.Sunday roasts are also common (though less so in recent times) in other Commonwealth countries such as South Africa, Canada and Australia. In Australia, roasts increasingly feature on the menus of cafes and restaurants, designed to cater to British backpackers. Jigg's dinner is a variation found in Newfoundland and Labrador, Canada. Typical elementsTypical meats used for a Sunday roast are beef, chicken, lamb or pork, although seasonally duck, goose, gammon, turkey or (rarely) other game may be used. Recently, vegetarian alternatives such as Quorn or nut roast have also become available. These are some of the common traditional accompaniments to various meats (although many people combine different types of accompaniments, or mix and match foods):roast beef — served with Yorkshire pudding; and horseradish sauce, or English mustard as accompaniments.roast pork — served with crackling and sage and onion stuffing; apple sauce and English mustard as accompaniments.roast lamb — mint sauce or redcurrant jelly as an accompaniment.roast chicken — served with pigs in blankets, chipolata sausages and stuffing, bread sauce, cranberry sauce or redcurrant jelly.Sunday roasts can be served with a range of boiled and roast vegetables. The vegetables served vary seasonally and regionally, but will usually include roast potatoes, roasted in meat dripping or (more recently, due to the perceived unhealthy nature of saturated fats) vegetable oil, and also gravy made from juices released by the roasting meat, perhaps supplemented by one or more stock cubes, thickened with some sort of roux, or corn flour. Other vegetable dishes served with roast dinner can include mashed swede or turnip, roast parsnip, boiled or steamed cabbage, broccoli, green beans and boiled carrots and peas. It is also common for prepared vegetable dishes — such as cauliflower cheese and stewed red cabbage — to be served alongside the more usual assortment of plainly-cooked seasonal vegetables. In Australia, roast pumpkin is almost universally served. It takes a considerable amount of domestic cooking skill and experience to have all the elements, with their separate cooking and preparation methods and timings, ready together to serve at their best.Left-over food from the Sunday roast has traditionally formed the basis of meals served on other days of the week. For example, meats might be used as sandwich fillings, lamb might be used in the filling for a Shepherd's pie, and vegetables might form the basis for bubble and squeak. Sunday Roast in pubs and restaurantsMany pubs in Britain serving food have a special "Sunday menu" that features a Sunday Roast, usually with a variety of meats available, and this is often cheaper than the normal menu.See also: Pub grub and Carvery
