Today I am smoking a 12lb turkey (using the recipe in the owners manual from masterbuilt) for the first time. I bought and am using one of the Walmart probes with alarm setting by Taylor. Recipe said to insert probe on the inside thigh area. Recipe also said cook would take 8-12hrs. thigh temp is at155 F after 5hrs in. Question.... should I trust reading when it reaches 180F or check breast with probe to be certain? Hope someone sees this before the cook is done.
