Liquid Food Thermometers for Cooking, Candy and Frying

For hot oil or candy, use a purpose-built high-temperature thermometer with a pot clip. For milk, sauces and soups, a clean instant-read probe may be more versatile if its range and immersion limits fit the task.

A liquid food thermometer is not one universal tool. Candy and deep-frying thermometers need a high enough range, a long stem and a secure clip that holds the sensor in the liquid without touching the pot. General instant-read probes can handle soups, sauces or milk when the maker permits the temperature and immersion depth.

Common questions

Questions before you buy

Can you use a meat thermometer for liquids?

Often, yes, if its temperature range, sensing area and water-resistance instructions suit the liquid. Do not immerse beyond the level allowed by the manufacturer.

What thermometer is best for hot oil?

Use a deep-fry thermometer with an appropriate high-temperature range, a long stem and a stable pot clip. Keep the sensor off the pan bottom.

Can a food thermometer touch the bottom of a pot?

No. The metal base may be hotter than the liquid and distort the reading; suspend the sensing area in the liquid.

Is a candy thermometer the same as a cooking liquid thermometer?

It is a specialized liquid cooking thermometer with a range and mounting style suited to sugar syrups. It may also cover frying, but check the maker's stated range and uses.
