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.
Heat the oven to 450 degrees. When the beef is at room temperature, place it in the roasting pan on top of the vegetables and put it into the oven. When a brown crust forms on the meat, usually in about 15 minutes, turn the heat down to 300 degrees. From here, slow cooking the meat will allow the flavors to develop.Allow the beef to cook. Here are internal temperatures for judging the stage the bottom round beef roast is at: 120 degrees to 125 degrees for rare; 130 degrees to 140 degrees for medium rare; 145 degrees to 150 degree for medium; 155 degrees to 165 degrees for well done.
