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.
However, when you are roasting shoulder, round or rump roasts, the doneness temperatures should be adjusted 5 degrees higher; for best results, cooking beyond 145 degrees is not recommended. For narrower-shaped cuts of beef, such as eye of round, roast at 170 degrees for 2 hours per pound.n general, roasts cooked using the slow-low method will follow the doneness temperature guidelines of 125 for rare, 130-135 for medium-rare and 140 for medium; that is particularly true of roasts from the rib or loin, especially the tenderloin.
