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.
Cook rump roast for at least 1 hour and 40 minutes for rare. Make sure that the internal temperature of the meat is at least 120 F before removing from the oven.
