A meat probe should be used to check the temperature of a pot roast. It is stuck into the thickest part of the meat and near a bone if one is present for the most accurate reading.
The internal temperature for roast duck should reach 160 to 165 degrees F.
This depends on how you want the finished roast, rare, med rare or well done. An hour at 350 degrees for rare, an hour and thirty for med rare and up to 3 hours for well done.
Get a digital probe thermometer (the kind with the silicone coated wire that plugs into a external unit-- $20 at Target or any kitchen supply store) and use that. Cover the roast with aluminum foil and cook at 350F until the center of the roast reaches 150 degrees Remove roast, and let rest covered until the internal temp starts to decrease. Do NOT remove the probe yet, lest the whole gush juice like a whale. Carry-over should bring the temperature to 160F. Turn the oven up to 500F Remove probe from roast, and uncover. Stick back in oven for 10 more minutes at 500F to create a crust on it. Let rest covered for 10 minutes or so. Some people actually do the last step first, then cook it at 325F.
165 degrees
When my mother cooks a roast, she uses a thermometer with a probe to stick into the meat, to see if it's fully cooked.
