If you make candy, chances are you have a candy thermometer. It is just one of those essential kitchen tools that get used for a specific job. You probably assume it is always accurate. Right? Maybe not. Maybe you need to check your candy thermometer before you start your next batch of candy.
Have you had it a long time? Are you sure your candy thermometer registers the correct temperature? Candy thermometers can change or lose their accuracy over time. It might be a good idea to check it. Making candy is one thing which relies on correct temperatures. You want your tools to be correct.
So…how do you check your candy thermometer? It isn’t hard. In fact, it would be good idea to check it every year before you start that big batch of candy for the holidays.
To check its accuracy, first fill a pot with water and place the candy thermometer in it. Just like making candy, make sure the bulb is fully immersed but not touching the bottom or sides of the pot.
Heat on high to boiling. Check the temperature on the thermometer. It should be 212 degrees.
Now, set a timer for five minutes. Check the temperature on the candy thermometer again. It should still be at 212 degrees. If so, your candy thermometer is accurate. If not, you have two choices. You could get rid of it. Or, you could try calibrating it.
To calibrate it, check the temperature when it’s in the boiling water. Let’s say the candy thermometer registers only 200 degrees. It means you will need to adjust the temperature in your recipe by 12 degrees. If your recipe wants you to get to a temperature of 235 degrees, you will need to actually get to 247, or 12 degrees hotter, on your thermometer. If you check your candy thermometer regularly, your candy will thank you.
Remember that the next time you use it. Or, write it down!
If that is something you don’t want to mess with, buy a new one. Then, test its temperature to make sure the new candy thermometer is accurate.
A good rule to follow when storing your candy thermometer is to store it upright. They are fragile and can break if hanging out in a catch-all utensil drawer.
