Frequently asked questions
What are the best kitchen thermometers?
The ThermoWorks Thermapen ONE is the best overall pick, an instant-read with 1-second readings and 0.5 F accuracy. The ThermoWorks ChefAlarm is the best leave-in probe, the OXO Candy & Deep Fry Thermometer suits candy and frying oil, the Taylor Mighty Mini is the budget pick, and the Combustion Predictive Thermometer is the premium wireless option. Pick the type that matches the job you do most.
What is the difference between an instant-read and a leave-in thermometer?
An instant-read model like the ThermoWorks Thermapen ONE or Taylor Mighty Mini is for quick checks and comes out of the food; Taylor says its Mighty Mini should not be left in food while it cooks. A leave-in model like the ThermoWorks ChefAlarm keeps its probe in the roast, with a heat-rated cable running to a base outside the oven that sounds an alarm at your target temperature.
How accurate does a kitchen thermometer need to be?
For meat, a degree or two matters most near your target. ThermoWorks rates the Thermapen ONE at ±0.5°F and the ChefAlarm at ±1.8°F between -4 and 248°F, and Combustion rates its Predictive Thermometer at ±0.4°F from 14 to 149°F. Taylor does not publish an accuracy figure for the Mighty Mini.
Do I need a special thermometer for candy and deep frying?
It helps, because you need hands-free readings in a hot pot. The OXO Candy & Deep Fry Thermometer clips to the pan and has large markings you can read from a distance. The ThermoWorks ChefAlarm also works, since its probe cable is rated to 700°F and it can alarm at a set temperature.
