Early escalators had stairs made of wood â which happens to burn, unfortunately. One of the most notorious escalator accidents in history occurred on November 18th, 1987, when a fire fanned by drafts in Londonâs Underground subway network killed 31 people.
Preheat your oven to 475 degrees F. Move your bottom round to a roasting pan, and place a meat thermometer into the thickest part of the beef. Step 3. Roast your bottom round at 475 degrees F for 30 minutes. Then, reduce the heat to 350 degrees F and continue roasting. Monitor the meat thermometer for your desired cooking level. Anything below an internal temperature of 130 degrees F is rare. Do not roast to an internal temperature of more than 140 degrees F or your roast will be medium, not medium rare.
The method of cooking a roast in a roaster is called braising. A three pound roast would cook aproximately 2 to 2 1/2 hours at 325. The inside temperature should be 140 degrees for rare, 160 degrees for medium, and 170 degrees for well-done. Use meat theomometer for this.+++Use a meat thermometer that you leave in the roast the entire time it cooks...it should reach the middle..and not hit a bone. Cook 22 minutes per lb. at 300 degrees. Answer   If frozen then a 4 lb. beef roast will cook faster. Put the oven up to 400 (lid on roaster) for 20 - 30 minutes and sear, then put the temperature down to â¦ 350 and cook 15 minutes per pound.   If the 4 lb. beef roast is thawed then sear as above and cook for 20 minutes per pound.
