Becca said:Tonight, I roasted a chicken until the thermometer read 180 degrees (F). I
always use a thermometer when I roast beef, chicken or pork.
Unfortunately, the chicken was not done, it was undercooked. Not believing
what I saw, I checked the chicken in 2 other areas, and it still read 180
degrees. Should I replace my thermometer?
BTW, I cooked the chicken for 15 more minutes, until the juices ran clear. I
had brined the chicken and it was delicious, I just can't figure out why the
chicken was not done.
This seems to happen to me a lot too. The pop-up thermometer on the chicken
(Perdue Oven Stuffer Roaster) will have popped, the thermometer will read 180
degrees, and yet the meat will still seem undercooked. The main thing is redness
around some of the bones. In my Joy of Cooking cookbook (which is a 30 year old
edition), it says that redness around the bones is normal on a very young
chicken because the bones aren't fully solidified (or some such term) yet and
the marrow leaks out. I don't know if all chickens today, even the big roasters,
are essentially young because they've bred them and fed them to grow extremely
fast. Aside from the temperature used to tell when it's done, maybe the juices
running clear is also good enough even if those bone areas still have redness. I
end up cooking a bit longer than either the pop-up or my digital thermometer
would indicate.
To check a thermometer, if you've got one of the digital ones you can test in
boiling water and make sure it reads close to 212 degrees. If it does, your
thermometer is probably also accurate at 180 degrees. You can also do this test
on other types of thermometers if they go up past 212 degrees.
