In different countries people like to roast different things. People usually roast joints of meats such as pork, beef, chicken, lamb, and duck. The roasted meat, along with its accompanying vegetables, is often called a roast.
Most meat being roasted has to cook for a relatively long time, to ensure the joint is cooked through. Variations to this include most joints of lamb and beef, which may be left "pink" or partially uncooked towards the centre.
