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.
Then place the first roast on a rack in a pan and place in a 275 degree oven. 20-30 minutes later, place the second roast (the one that needs to be rare) in the oven with a probe thermometer. Roast until it hits 112-115 degrees...then test the other one. Hopefully the other will be up to temp.hen place the first roast on a rack in a pan and place in a 275 degree oven. 20-30 minutes later, place the second roast (the one that needs to be rare) in the oven with a probe thermometer.
