The recommended method for obtaining an accurate reading on a thermometer involves ensuring there are no barriers between the thermometer and the food. This ensures that the thermometer can accurately measure the temperature of the food itself without interference from materials that could insulate or block the heat transfer. Barriers such as plastic wrap, containers, or even a thick crust of food can lead to a false reading, indicating that the internal temperature may not be accurately conveyed.

While inserting the thermometer deeply into the food is important for reaching the center where it is hottest, if there are barriers present, the reading may still be inaccurate. Placing the thermometer directly on the food does not allow for an accurate measurement of the internal temperature, as the surface temperature can be significantly different from the temperature further inside. Holding the thermometer away from the food altogether would provide a reading that is not relevant to the food's actual temperature.

By ensuring that the thermometer sensor is in direct contact with the food without any intervening barriers, the most precise temperature reading is achieved, which is critical for food safety and ensuring that food is cooked or held at safe temperatures.
