Post by ccs06 on Nov 12, 2008 at 7:47am. Any advice for cleaning ceramic tile with textured grooves in it? 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.
Here's how you do it: 1  Cook the beef at 350F until its internal temperature reads 5-10 degrees below the desired doneness. 2  It'll take anywhere from 15 to 30 minutes per pound, depending on the shape of the roast, and how well done you like it. 3  Remove the roast from the oven, and let it stand for 20 minutes. This can take 4 to 8 hours depending on the size of the roast, and how cooked you like it. 2  Turn the heat up to 500F and cook it until it reaches 5 to 10 degrees below the desired doneness. 3  It shouldn't take much more than 10-15 minutes. 4  Remove the roast from the oven and let it stand about 20 minutes.
