What type of probe should be used to check the temperature of a large stockpot of chili?

An immersion probe is specifically designed for measuring the temperature of liquids. When checking the temperature of a large stockpot of chili, an immersion probe allows for accurate readings by being submerged directly into the liquid. This is essential for ensuring that the entire mass of the chili reaches a safe cooking temperature, as it can provide a measurement that reflects the temperature of the chili throughout, rather than at just the surface level or at a single point.

Choosing an immersion probe is particularly important for larger quantities like a stockpot, where heat distribution may not be uniform. It ensures that even the temperature of the deepest parts of the chili can be measured effectively, which is crucial in preventing foodborne illness by ensuring that it reaches the necessary temperature for safety.
