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.
Step 1. 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.enerally, the final internal temperature, according to the U.S. Department of Agriculture, for a medium-rare pot roast should be around 145 degrees F after 15 to 20 minutes of standing time. The final internal temperature for a medium-done pot roast should be around 160 degrees after 15 to 20 minutes' standing time.
