Probes with different temps - which one to believe
« on: August 15, 2020, 02:41:06 PM »
Right now I am smoking a pork belly.  I am doing about half of it in one big slab, the other half I have cut into cubes for burnt ends.

Using my Thermoworks Signals I have two probes in the slab and they are reading about 15 degrees different.  Which one should I trust?  I am guessing the one with the lower temp as it is probably closer to the middle of the meat whereas the other probe is likely to too close to the top or bottom of the slab.  Is that the right way to handle this?  Or should I average the two probes?  Or believe the higher temp?

FYI - the slab is currently wrapped in foil, but I had the same issue prior to wrapping.  I am doing pretty much a 3-2-1 type of technique for both the slab and burnt ends.

There could be a number or reasons two probes in the same cut of meat are reading differently; especially in a cut like pork belly; but 15 degrees is a lot. First make sure your probes are fully inserted into their connection. I have a Signals, and once I was getting reading from one probe that didn't seem right, and it was because it was not fully inserted. But in this case one probe may be in meat, and the other probe in fat. To get a more accurate reading, when this happens I generally will move the probes in and out to find the lowest reading, or relocate the probes, and then go by the lowest reading.

I generally use remote food probes as a guide, and always check with an instant read thermometer, and if it is a large piece of meat I will check in several areas. Also the pork belly, and the burnt ends may be better if you finish them off with higher heat to crisp the skin on the belly, and to better carnalize the sauce on the burnt ends.
