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 the roast fat-side up so that as the fat melts it bathes the entire roast in flavor. 4 Cook the roast initially at 375Â°F (190Â°C) for half an hour, to brown it. Then lower the heat to 225Â°F (107Â°C). The roast should take somewhere from 1 1/2 to 2 1/2 hours additionally to cook.The shape of the roast will affect the cooking time.If your roast is long and narrow, rather than a more round shape, it may take less time to cook, so keep an eye on it. When juices start to drip from the roast, and it is browned on the outside, check the roast's internal temperature with a meat thermometer.lace the roast fat-side up so that as the fat melts it bathes the entire roast in flavor. 4 Cook the roast initially at 375Â°F (190Â°C) for half an hour, to brown it.
