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.
Place roast in a heavy roasting pan. Insert meat thermometer so that the tip of the thermometer is in the center of roast, and not touching any bones (if there are any bones). Place roasting pan in pre-heated oven. If roast is less than 3 pounds: roast meat at 425 degrees for 20 minutes.If the roast is 3 pounds or larger: roast at 425 degrees for 30 minutes. (If a roast is very small - 1.5 pounds-it may be finished now-check the meat thermometer.). Without opening oven, reduce heat to 300 degrees.lace roast in a heavy roasting pan.
