Question

question 5
how far into the food should you insert the stem of a bimetallic stemmed thermometer to get an accurate reading?
up to the dimple
up to the tip of the probe
up to the calibration nut
up to the indicator head

Explanation:

A bimetallic stemmed thermometer's stem should be inserted up to the calibration nut. This is because the calibration nut marks the point where accurate temperature sensing occurs. Inserting beyond or before this point (like up to the dimple, tip of the probe, or indicator head) won't give an accurate reading as the sensing mechanism is calibrated at the nut.

Answer:

Up to the calibration nut
