Is Your Thermometer Reading Correct Recipe

Ingredients

How to make it

  • We contacted ThermoWorks (www.thermoworks.com), maker of the Thermapen, and a company representative faxed us calibrating instructions. After removing the back label, which covers the two calibration adjustment screws, we placed the tip of the probe in ice water (being careful not to let the probe tip touch the container) and adjusted the “Zero” screw (on the right) until the temperature read 32 degrees. Then we repeated the same test, this time using boiling water and adjusting the “Span” screw (on the left) until the thermometer read 212 degrees. (You’ll need to adjust for the fact that the boiling temperature of water drops 1 degree for every 500-foot increase in elevation above sea level.)
  • If you have a dial-face thermometer, the process is even simpler. Just immerse the thermometer in a slurry of ice water (boiling temperature calibration is not necessary), being careful not to touch the container and, using a pair of needle-nose pliers, adjust the screw on the underside of the dial face until it reads 32 degrees.

    Maybe I should use one more often, but I rarely use a thermometer of any kind. One exception is keeping sourdough starters within a certain temperature range - and my room thermometer usually gives me the information I need. If you are working with boiling sugars and the like, I can see why temperature can be very important. If you are cooking a very low temperatures, say 140 F, accurate temperature readings are a must both for the cooking device and for checking meat temperatures.
