Analyse seems to have been the more common spelling in 17th- and 18th-century English, but many of the great dictionaries of that time â John Kersey's of 1702, Nathan Bailey's of 1721 and Samuel Johnson's of 1755 â prefer analyze. In Canada, -yze prevails, just as in the US.
Oven Cooking. To slow-cook a rump roast in the oven, set the oven to 250 F. At this temperature, the roast will cook in about four hours, depending on the size of your roast. Place the roast in an oven-proof pot or Dutch oven with a lid. Add 1/2 to one cup of broth or red wine, so that the roast is partially covered.
The cooking temperature and other variables, such as the weight of the pot roast, determine the length of cooking time required. Preheat your oven to 325 degrees Fahrenheit for a pot roast from the round; 425 degrees for a pot roast from the chuck; and 350 degrees for a pot roast from the rib.The weight and type of roast determines the cooking time; you should cook a roast until its internal temperature is between 135 and 150 degrees F.For instance, a 2- to 3-lb. rump roast cooks for 1 Â½ to 2 hours to medium-rare doneness, the Cattlemen's Beef Board and National Cattlemen's Beef Association website advises.emove the pot roast from the oven when it is 5 to 10 degrees below the recommended final internal temperature. Cover the roasting pan loosely with a tent of aluminum foil and let the roast stand for 15 to 20 minutes. The internal temperature of the roast will rise another 5 to 10 degrees.
