They are not to be trusted. I used one on my turkey. Why?
Well, I had never used one before and I owned one, I thought its time to see if this would help make sure I did not overcook the bird.
It said the breast meat was 180 degrees which is 20 over what is considered done.
Its wasn't raw but it could have taken another 30 minutes. The joints were not free yet and the browning was not really there. I was afraid I had overcooked it but that was not the case.
You win some, you lose some.
Taste was fine. But it wasn't the best turkey I ever roasted.
Back to my old tried and true methods. The legs must be almost free and ready to come off the bird.
