What is a Candy Thermometer?


A candy thermometer or sugar thermometer is used to measure the temperature of cooking sugar. It is used to reach the proper temperature in the candy making process.Sometimes, it can also be used as a deep-fry thermometer or jam thermometer.

Candy thermometers are almost the same as meat thermometers. The only difference is they are calibrated to reach higher temperature ranges that are required when cooking sugar or candy.

Because candy reaches a very high temperature, some candy thermometers do not come with low temperature ranges. Although, there are a lot of multifunctional thermometers on the market today that has a wide range of temperature. These already include freezing up to above boiling, so you can use this when making candy and other food.

Why Use a Candy Thermometer?

The candy making process is very tedious and it follows strict temperature rules to achieve the best results. That’s why buying a thermometer for this purpose is very important. Getting the right temperature while cooking is very crucial to the end result of the candy. Having just a little difference can change the consistency, texture, or flavor.

What Are The Features To Look For

Before buying a candy thermometer, here are some things you should consider:

  • Are you going to use it for candy only or other food items also?
  • What type of pot will you be cooking the sugar? You should choose a thermometer that is long enough to read the temperature but safe from touching the bottom of the pot.
  • Digital or analog? Glass or metal? Each type of thermometer reading has their advantages and disadvantages. And each also has their own unique features which we will discuss later in the article.

Digital vs Analog

Analog thermometers are very common and easy to find, but it can take time before they settle on the right reading. Meanwhile, digital thermometers deliver the temperature fast electronically and will even alert you with a beep if you’ve reached the temperature you are looking for.


You’ll be using your thermometer for making sugar candy so temperature accuracy is crucial to achieving the best and most consistent end product. One way to check your thermometer’s accuracy is by boiling some water and using the thermometer to check the temperature. It should come to 100 °C or 212 °F because this is the boiling point of water.

If it doesn’t come to this temperature then you have to calibrate it yourself. The thermometer’s manual usually contains instructions on how to calibrate it. We also have instructions below on how to calibrate a thermometer.


Not all thermometers are made to be the same; thus, pricing may vary from one brand to another. Generally, an analog thermometer is cheaper but the downside is that it performs slower, hard to read and can be inaccurate sometimes.

On the other hand, a digital model can be pricey but it is user-friendly and has additional features that are helpful for cooking. Besides, it has all bell and whistle that it is impossible to have on an analog model.

Types of Thermometers


Here are the different types of thermometers and their different features.

Analog Thermometer

Analog thermometers usually contain mercury or spirits that react to the heat. It rises and moves through the thermometer to give you a temperature reading. This type of thermometer is usually affordable but can take a longer time to produce a reading.

Digital Thermometer

Digital thermometers are very easy to read compared to analog thermometers. This type of thermometer reads temperatures accurately and gives results faster on its digital display.

There are some digital thermometers that come with an alarm to let you know about the temperature result. Some also have markers for different stages of the candy making process such as soft ball, firm ball, and hard ball stage. This is very useful for those who are regularly making candy.

Glass Thermometer

Glass thermometers are usually tube-shaped and come with a clip to easily attach to the side of the pot while cooking. Some are enclosed in glass protectors to avoid touching the side of the pot and prevent breaking. On its back can include temperature ranges for different stages of heat which comes in handy when cooking.

Metal Thermometer

Metal thermometers often have a 7 to 8-inch probe and can be either analog or digital. This comes with a clip to easily attach to the side of the pot. Analog metal thermometers have a round dial face, similar to a clock, for the temperature reading. On the other hand, digital metal thermometers have a case that displays the temperature reading.

How To Calibrate A Thermometers

Analog and digital thermometers both need calibration once in a while, especially with constant use. While digital thermometers are reliable for a longer period, analog thermometers require frequent calibration.

Often times, to calibrate a thermometer, you need to put it in freezing or boiling water than manually adjust it. If there is no manual adjust option on your thermometer, then it is better to buy a new one for a more accurate temperature reading.

However, for candy thermometers, only the boiling water method is necessary because most of these thermometers don’t have a reading for freezing temperature. Also, keep in mind not plunge the thermometer in boiling water to avoid breakage. For more detail steps in calibrating a thermometer, refer to How to Test Your Candy Thermometer.

How to Use a Candy Thermometer?

Let the sugar and water boil over medium to high heat. When it is already fully boiling, lower the heat to medium but it should be hot enough to keep it boiling. Insert the candy thermometer slowly but avoid it from touching the sides or bottom of the pot to achieve an accurate reading and to prevent the of risk ruining the thermometer.

Let the mixture boil until it reaches the proper temperature or stage you want to achieve and remember to stop at that point. The temperature shouldn’t be less or more so that you have a consistent candy texture.

Wrapping Up

We’ve just reviewed the best candy thermometers on the market, but it is still up to you to choose which one suit you the most. And as you make your candy, keep in mind that temperature accuracy is very critical to achieving the best outcome. That’s why having a reliable thermometer will come in handy in the kitchen.

There is other well-known candy thermometer brand on the market besides what we featured above. Individually, the Taylor, Norpro, Williams Sonoma, Polder and Maverick CT-03 are famous brands but from what we found through our research, all these brands have low customer satisfaction level. Whereas our recommended list above is all high quality, has ample of good ratings as well as high customer satisfaction level.

As you shop for a candy thermometer, remember the different features that you should look for. Knowing these will help you make the best out of your purchase and will help you in cooking or baking. For us, we’ve chosen digital thermometers because it can give faster and more accurate temperature readings compare to analog.
