Pop-up turkey thermometers can suck

barfblog, by Ben Chapman on Nov. 27, 2017 

I usually pull the pop-up thermometer out of my bird when I cook it. I'm a digital-tip-sensitive thermometer kind of guy. Last Thursday, while roasting this year's turkey, I left mine in, as a bit of an experiment for my graduate student Minh, like last year's Consumer Reports pop-up test:

We tested 21 pop-up thermometers in whole turkeys and turkey breasts. Our testing covered pop-up timers bought online and put into place by cooks before sliding the bird into the oven, and models pre-inserted in the meat at the processing plant. To determine the pop-ups’ accuracy, we also measured the internal temperature of the meat with a calibrated reference thermometer. Our findings may make a few eyebrows pop:

Self-inserted and manufacturer-inserted timers generally “popped” in our tests at internal temperatures above 165° F—the minimum safe temperature for all poultry. But three timers popped up when meat was still below that safe zone, one as low as 139.5° F.

Thanks pop-ups, I was only 20F (and 75 min of roasting) short.
