Peanut Brittle
Peanut Brittle FAQ
Why do the peanuts pop while cooking?
As they heat up, moisture inside the peanuts turns to steam, causing them to pop. This is a sign they are roasting properly.
Why is baking soda used in peanut brittle?
Baking soda reacts with the sugar mixture, creating air bubbles that make the brittle light and crisp.
Can I use raw peanuts instead of shelled peanuts?
Yes, raw peanuts work best because they roast while cooking.
How do I prevent the brittle from sticking?
Use a well-greased baking sheet or parchment paper to prevent sticking.
How should I store peanut brittle?
Store it in an airtight container at room temperature for up to two weeks to keep it crisp.

Food History
Peanut brittle dates back to the 19th century and has long been a favorite homemade candy. Some stories suggest it originated in the Southern U.S., while others believe it was created by accident when a cook mistakenly used baking soda instead of cream of tartar. Either way, peanut brittle became a popular treat, especially around the holidays.

Recipe Discussion
This peanut brittle recipe creates a perfectly golden, crisp candy with a deep caramelized flavor. The peanuts add a rich nuttiness, while the baking soda ensures a light, airy crunch. Cooking over medium heat allows the sugar and corn syrup to reach the right consistency without burning.
The key is to watch the peanuts closely—once they pop and look roasted, it’s time to remove the mixture from the heat and stir in the baking soda. This step gives the brittle its signature texture.
Preparation Tips
- Use a candy thermometer – The sugar mixture should reach 300°F (hard crack stage) for the best texture.
- Stir at intervals – This prevents burning and ensures even cooking.
- Work quickly when adding baking soda – The mixture will foam and harden fast.
- Use a greased cookie sheet or parchment paper – Prevents sticking and makes cleanup easier.
- Break into pieces once fully cooled – The brittle should snap easily when broken.
