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.
Season the roast, sear it in hot oil and cook it in a 250 degree Fahrenheit oven for roughly 30 minutes per pound. One of the keys to keeping it tender is to slice it very thin just as you find in a delicatessen. In fact, if you purchase roast beef in a deli, there is a good chance you are getting rump roast.
