The tile also has little pit holes in it to that the dirt just gets in and sticks as well as along the grove lines. This is in a high traffic area so it is dirty nightly. I started cleaning with a scrub brush and then moved to a handled angled brush to get in the crevices better, but it takes forever and it never looks absolutely clean.
In an oven heated to 275 degrees you cook a roast for 28 minutes per pound. Therefore the estimated cooking time for a 4.8 pound roast is 134 minutes or 2.23 hours.
Plan on oven-roasting the rump roast at 325 degrees Fahrenheit for about 28 to 33 minutes per pound for medium-rare meat, though the exact cooking time will vary depending on the roast's shape and size. Begin checking the meat after 45 minutes and continue checking it every 15 minutes after that.Remove it from the oven when a meat thermometer inserted into the thickest part of the roast registers 140 degrees Fahrenheit. For the slow cooker method, allow the roast to cook on the low setting for eight to 10 hours.hoto Credit Kathy Burns-Millyard/Demand Media. To keep rump roast juicy in the oven, you'll need to add a liquid like beef broth. Place the seared roast into the pot or roasting pan with the fat layer facing up and pour in a can of low-sodium beef broth, or approximately 2 cups of beef stock.
