Can You Use a Meat Thermometer for Candy?

You’re halfway through a recipe for beautiful homemade caramel or crunchy peanut brittle. The sugar is melting, the butter is bubbling, and the recipe calls for you to bring the mixture to the “soft-ball stage.” You reach for your candy thermometer, only to realize you don’t have one. In the drawer, however, is your trusty meat thermometer. Can you make the swap? It’s a common kitchen dilemma. This guide will give you the clear, expert answer and explain the crucial differences between these two precision tools.

The Short Answer: It’s Not Recommended, and Here’s Why

While they both measure temperature, a meat thermometer and a candy thermometer are designed for very different jobs. For the best and safest results, we do not recommend using a standard meat thermometer for making candy. There are three key reasons for this:

1. Temperature Range: Candy making often requires temperatures well above 300°F (149°C) for “hard-crack” stages. Many meat thermometers, especially older digital models, have a maximum temperature that is below this range and can be damaged by such high heat.
2. Design and Safety: A candy thermometer is long and designed to be clipped to the side of a pot for continuous, hands-free monitoring. It keeps the display away from the hot, bubbling sugar. A meat thermometer is designed for quick insertion into solid meat; its shorter probe and handheld design put your hands dangerously close to hot steam and potential sugar splashes.
3. Accuracy in Context: Candy thermometers are built and calibrated for extreme precision within the specific stages of sugar cooking. A meat thermometer is calibrated to be most accurate in the lower temperature ranges required for cooking meat.

When Could You Use a Meat Thermometer in a Pinch?

Let’s be realistic—sometimes you have to make do. If you are in a bind, you might be able to use a high-quality digital instant-read thermometer for a quick spot-check, but only if you follow these rules:

• Check the Range: First, verify that your meat thermometer’s maximum temperature range is higher than what your recipe requires. If your recipe calls for 300°F and your thermometer maxes out at 250°F, do not attempt it.
• Do Not Leave It In: This is critical. An instant-read thermometer is not designed for continuous immersion in hot liquid. You can only dip the probe tip in for a few seconds to get a quick reading, then immediately remove it. Leaving it in the pot will destroy it.
• Be Extremely Careful: Keep the electronic body of the thermometer far away from the hot pot and rising steam to prevent damage and to protect your hands from burns.

The Right Tool for the Job: Why a Candy Thermometer is a Worthy Investment
