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.
Continue to cook the rump roast for at least 2 hours for medium.. The thermometer should read 155 F. Continued cooking may cause the roast to become tough and dry or burn the vegetables. Remove the rump roast from the oven and carve in slices. Serve with vegetables.
