ThermoWorks SuperFast Thermapen - It Tests Temperature Not Doneness; It Doesnt Lock in on a Reading; Heres What Your Thermapen DOES Do

76 Using Your Thermapen Your Thermapen - A Guide to Better Food
It doesn't test doneness; it only tests the
current temperature
While temperature is the most effective indication of the doneness
of food while it is cooking, cooked food will eventually cool. For
example (although you might be tempted to try), it wouldn’t do
you much good to take your Thermapen
to a restaurant so you
can test your steak as it arrives at your table. Your Thermapen
would only tell you the temperature of the steak at the table, not
the highest temperature the steak reached in the kitchen - which
would be the temperature that determined its doneness. While
cooking, remember to look for the highest temperature reached
in the thickest part of the food to judge doneness (see 'Outdoor
Grilling' on page 14).
It doesn’t lock in on a reading
If you find that the digits on your Thermapen readout keep
changing after three seconds, that’s because the temperature at
the tip is changing. When you first penetrate meat on the grill,
for example, the Thermapen display will change very rapidly as it
moves from ambient temperature to the temperature of the meat
being probed. Within three seconds, the rate of change will slow
dramatically giving you an accurate reading, but it will not stop
changing completely. As the meat continues to cook and the
tip of your probe moves through the meat, your Thermapen will
continue to detect variations in the temperature of the meat itself.
