History of Peanut Brittle
Peanut brittle has a rich and storied history that dates back to ancient times, with roots tracing back to Europe. The earliest versions of peanut brittle can be found in countries like Spain and Portugal, where similar confections were made with nuts and sugar. Over time, the recipe made its way to America, particularly during the 19th century when peanuts became widely cultivated in the southern United States. As a result, the beloved peanut brittle we know today began to take shape, transforming from its European origins into a uniquely American treat.
The evolution of peanut brittle continued as it spread across various cultures, each adding its own twist to this classic confection. In Southern American cuisine, the use of peanuts became synonymous with regional cooking, and flavors began to expand with the introduction of local ingredients. Over the decades, variations emerged, including the incorporation of chocolate and different types of nuts, each variation enhancing the basic recipe’s appeal and versatility.
The introduction of spicy flavors into peanut brittle can be attributed to a growing interest in bold and adventurous combinations in food. Jalapeños, with their bright flavor and heat, have been embraced as a unique addition, elevating the traditional sweet treat into something that tantalizes the palate. This fusion of sweet and spicy is not just a trend; it reflects a broader culinary movement that celebrates the interplay of contrasting flavors, making jalapeño peanut brittle a creative and exciting option for snack enthusiasts.
Why Jalapeño Peanut Brittle?

Beyond its exciting flavor profile, jalapeño peanut brittle boasts several health benefits.

When combined, these ingredients create a treat that is both delicious and health-conscious, appealing to those looking to satisfy their sweet tooth while also enjoying some nutritional perks.

Detailed Recipe for Jalapeño Peanut Brittle
Preparation
Before you start making your jalapeño peanut brittle, prepare your workspace and gather your tools. You will need a heavy-bottomed pot, a baking sheet lined with parchment paper, a heat-resistant spatula, and a candy thermometer for best results.
Ingredients
- 2 cups peanuts
- 1 cup granulated sugar
- ½ cup light corn syrup
- 1 tablespoon unsalted butter
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1-2 fresh jalapeños, finely chopped, or 1 teaspoon jalapeño powder
Directions
- Cooking the Sugar Mixture: In your heavy-bottomed pot, combine the sugar, corn syrup, and a splash of water. Stir gently over medium heat until the sugar dissolves. Allow the mixture to boil without stirring until it reaches 300°F (hard crack stage) on your candy thermometer.
- Incorporating Peanuts: Once at temperature, carefully stir in the peanuts and continue cooking for another 3-5 minutes, stirring constantly until the mixture reaches 290°F.
- Adding Jalapeño: Remove the pot from heat and quickly mix in the jalapeño and baking soda. The mixture will bubble up, so be cautious.
- Finishing: Pour the mixture onto the prepared baking sheet, spreading it out evenly with your spatula. Allow it to cool completely.
- Breaking the Brittle: Once cool, break the brittle into pieces and store in an airtight container.
Advice for Perfecting Your Brittle
Utilize a candy thermometer for accuracy in temperature. If you prefer a milder flavor, adjust the amount of jalapeño to suit your taste. Store your brittle in a cool, dry place to retain its crispness for a longer duration.
Variations of Jalapeño Peanut Brittle
Different Nuts to Consider
You can easily substitute peanuts with other nuts such as almonds or pecans. Each nut alters the flavor and texture slightly, contributing to a variation that can be just as delicious while offering a different taste experience.
Varying the Spice Level
Adjust the spice level to your preference by using fresh jalapeños for a more intense heat or dried/powdered versions for a milder flavor. You can also increase or decrease the quantity based on the desired spiciness.
Chocolate Coating Option
For an extra layer of indulgence, consider adding a coating of melted chocolate—dark or white—over your cooled brittle. Simply melt your chocolate, drizzle it over the brittle, and let it set before breaking into pieces.
Serving Suggestions
Jalapeño peanut brittle makes a fantastic pairing with cocktails, offering a sweet-spicy contrast to drinks like margaritas or whiskey-based cocktails. Present it in decorative bowls for parties, and consider creative packaging options for gifting to friends and family.
Common Mistakes When Making Brittle
