How far must a bimetallic stemmed thermometer be inserted into food to give an accurate reading?

A bimetallic stemmed thermometer provides the most accurate readings when it is inserted up to the dimples located on the stem. The dimples indicate the proper point for the sensor that measures the internal temperature of the food. When the thermometer is placed at this point, it ensures that the sensing area is fully surrounded by the food, eliminating the influence of surface temperatures and yielding a more accurate core temperature reading.

Inserting the thermometer at least 2 inches deep may not be necessary for all types of food and could lead to inaccurate readings if placed too deeply or not centered. Similarly, only inserting the tip or just 1 inch below the surface wouldn’t provide a reliable measurement, as these methods could result in reading temperatures that are either too cooled or not representative of the food's core temperature. Thus, the correct practice firmly rests on the depth indicated by the dimples on the thermometer, ensuring effective food safety measures.
