Recipes that use a candy thermometer

Recipes that normally use a candy thermometer include, but not limited to, soft and hard candies, nut brittle, dark chocolate, fish fry, toffees, bark, fudge pops, fried chicken, and fried Oreos. However, with a versatile all-in-one candy thermometer, you can even monitor your meat’s temperature.

Do candy thermometers have mercury in them?

Most of the candy thermometers don’t have mercury in them. If a thermometer has a silvery liquid and is not labeled as “mercury-free”, it’s probably using mercury to give you temperature readings. Mercury thermometers are almost obsolete these days; because of the health concerns attributed to mercury. A digital candy thermometer that uses the battery is commonplace today.

What temperature does a candy thermometer go to?

A candy thermometer is meant to measure the temperature of a recipe boiling on a stove. Meat or cooling thermometers typically measure lower temperatures than a candy thermometer. Normally, a candy thermometer goes up to 400°F to ensure high-temperature measurements with high accuracy.

Candy thermometer vs. cooking thermometer

Both are similar except their temperature reading range. Candy thermometers typically cover a higher temperature range, going up to 400°F, while most cooking/meat thermometers read up to 200°F.

Can you use a meat thermometer for candy?

A candy thermometer normally can be used as a meat thermometer. Still, the other way around is not a very good idea. A meat thermometer can only go as far as 200°F, and it won’t tell you anything above this temperature. A melted sugar will be higher in temperature than steak, so it’s not recommended that you use a cooking thermometer for your candies or sugar recipes. It’s not designed to measure or even endure such high temperatures.

Can I use a candy thermometer for oil?

A candy thermometer is an ideal device to measure oil temperatures. The reason is its ability to take very high-temperature readings. Around 370°F would be a perfect temperature for frying; a candy thermometer is equipped to measure up to 400°F.

How to calibrate a candy thermometer?

The purpose of calibration is to make sure your thermometer is measuring accurately. Water’s boiling temperature is the most useful baseline for this. Place the thermometer into a pot of water and bring the water to a consistent boil. Monitor the reading; if it stops at 100°C/212°F, you are good to go. If not, adjust the position of the thermometer until it shows the boiling temperature of the water.

How to check the candy thermometer for accuracy?

You can use the calibration method to check whether your thermometer is showing accurate readings or not. Water boils at 212°F temperature. If your device shows this temperature while inside boiling water, it’s accurate.

How much does a candy thermometer cost

A candy thermometer is an inexpensive and handy tool for bakers. Depending on the quality and technology, it can be as low as $7 or as high as $35. But, a decent digital candy thermometer costs around $15 on average.
