Peanut Brittle Tips

Do I need a candy thermometer to make this easy peanut brittle recipe?

Yes! You don't want to be guessing the temperature when making brittle. A candy thermometer is handy when making this recipe.

Why is my peanut brittle not crunchy?

Chances are, if your brittle is soft, you didn't cook the sugar mixture long enough or bring it up to the right temperature. Be sure to check your candy thermometer prior to each use to make sure its accurate. Here are more tips on how to make candy that you'll find useful when making brittle and other sweets!

Can you use other types of nuts to make easy peanut brittle?

Yes! Substitute your favorite type of nut for the peanuts if you are looking for some variation. You can use cashews, almonds or even a mixed variety to make an almond brittle or a pistachio brittle.

How can you replace the corn syrup in peanut brittle?

If you want to replace the corn syrup, use golden syrup since it has identical properties and will work just as well. Other sweeteners might not work because they crystallize, so double-check before making any swaps.
