Which probe should be used to check the temperature of a large stock pot of chili?

  1. Surface probe

  2. Penetration probe

  3. Immersion probe

  4. Air probe

The correct answer is: Immersion probe

When checking the temperature of a large stock pot of chili, an immersion probe should be used. An immersion probe is designed to be submerged into liquids or semi-solid foods like chili to accurately measure the temperature. This type of probe ensures that the temperature reading is taken from the center of the food being cooked, which is important for food safety. Surface probes are used to measure the temperature of flat surfaces, penetration probes are used for thin foods like burgers or chicken breasts, and air probes are used to measure the air temperature inside ovens or refrigerators.
