Ingredients
- 1 cup granulated sugar
- 1/2 cup light corn syrup
- 1/4 cup unsalted butter
- 1 cup roasted peanuts
- 1-2 fresh jalapeños, finely chopped
- 1/2 teaspoon baking soda
- 1 teaspoon vanilla extract
- Salt to taste
Step-by-Step Instructions
- Prepare the Baking Sheet: Line a baking sheet with parchment paper and set aside. This will be where you pour the brittle once it’s cooked.
- Cook the Sugar Mixture: In a medium saucepan over medium heat, combine the granulated sugar, light corn syrup, and butter. Stir constantly until the mixture comes to a boil.
- Add the Peanuts: Once boiling, add the roasted peanuts and chopped jalapeños. Continue stirring to ensure everything is well-coated in the mixture.
- Monitor the Temperature: Use a candy thermometer to monitor the temperature of the mixture. Continue to cook until it reaches 300°F (hard crack stage). This usually takes about 8-10 minutes. Be careful not to burn the mixture!
- Add the Rest of the Ingredients: Remove from heat and quickly stir in the baking soda, vanilla extract, and salt. Be ready; the mixture will bubble up!
- Pour the Mixture: Immediately pour the hot mixture onto the prepared baking sheet. Spread it out evenly and let it sit until fully cooled—at least 20 minutes.
- Break Into Pieces: Once cooled, break the brittle into manageable pieces and enjoy!
Top Tips for Perfecting Spicy Sweet Jalapeño Peanut Brittle
- Substitutions: Want to kick the spice level up a notch? Try adding a dash of cayenne pepper for added heat. If you can’t find fresh jalapeños, feel free to use pickled ones instead for a unique tang!
- Timing: Watch the temperature closely; if the mixture cooks too long, it may become too hard or burn. If it cooks too short, it may not set properly.
- Common Mistakes: Make sure to get every ingredient measured and ready before starting. The candy process cooks quickly, and you won’t have time to stop!
Storing and Reheating Tips
To keep your Spicy Sweet Jalapeño Peanut Brittle tasting fresh, store it in an airtight container at room temperature. It will stay fresh for about 2 weeks—if it lasts that long! If you wish to save some for later, it freezes perfectly—just wrap individual pieces in wax paper and seal them in a freezer-safe bag. When you’re ready to enjoy again, simply let it thaw at room temperature and crunch away!
Now, gather your ingredients and make this tasty treat! Not only will it wow your family and friends, but it may just become a cherished recipe passed down through the generations. Happy cooking!
