Candy thermometers are a MUST when it comes to making different types of delicious desserts. Recipes for candy making or sugar syrups, like fudge, fondant, toffee or butterscotch always need some sort of thermometer to help with the cooking process.
However you should always test your thermometer periodically by placing it in boiling water. At sea level, water boils at 212 degrees F/ 100 degrees C. If your candy thermometer reads below or above this number, you’ll need to buy a new one or adjust the temperature you’re looking for in boiling point based on the difference shown.
For every 500foot (150m) increase in elevation, water’s boiling point is lowered by approximately 0.5 degrees C. If it’s too tricky to calculate what’s the boiling point at your level, you’ll definitely be able to get a quick answer on the internet.
Experts recommend using a Fahrenheit thermometer because, apparently, the variation on Celsius scale is not accurate enough when candy making. Don’t forget to store your thermometer in a safe place and handle carefully.
Some internet resources are advising against making candy or syrup when it rains or snows. Well, it has not been demonstrated that the humidity has anything to do with influencing the boiling point. It is the change in elevation that you’ll need to take in consideration.
