Ingredients

  • 1 cup sugar
  • 1/2 cup water
  • 1/2 teaspoon butter
  • 1/4 cup light corn syrup
  • 1 cup salted cashews
  • 1/8 teaspoon baking soda

Instructions

  1. Combine sugar, water, light corn syrup, and butter in a saucepan. Stir over medium heat until the mixture reaches 300°F on a candy thermometer.
  2. Add cashews to the saucepan and cook until the thermometer reaches 310°F.
  3. Stir in baking soda quickly and thoroughly.
  4. Pour the hot mixture into a lightly greased 9-inch square pan.
  5. Smooth out the mixture to fill the pan evenly.
  6. Allow the brittle to cool until hardened, then break into pieces.

Tips & Substitutions

For a smoother texture, ensure your sugar mixture is well combined before adding the cashews. If you don't have light corn syrup, you can substitute with honey or agave syrup, though the flavor may vary slightly. Keep an eye on the temperature, as sugar can burn quickly past 310°F. For a unique twist, try adding a pinch of cinnamon or nutmeg for added warmth.

Serving Suggestions

Serve cashew brittle as a delightful snack or dessert on its own, or pair it with a scoop of vanilla ice cream for an indulgent treat. It also makes a wonderful gift or party favor, especially around the holidays. For an elegant presentation, serve with a side of the Elegant Amaretto-Chocolate Mousse to create a decadent dessert platter.

Storage & Reheating

Store the cooled cashew brittle in an airtight container at room temperature for up to two weeks. To keep it fresh, separate layers of brittle with parchment paper to prevent sticking. If you need to reheat it, place it in a warm oven for a few minutes to regain its crispness, but avoid microwaving as it can become chewy.

Frequently Asked Questions

Can I use unsalted cashews instead of salted?

Yes, unsalted cashews can be used, but you might want to add a pinch of salt to the mixture to enhance the overall flavor. This will balance the sweetness of the sugar and corn syrup, creating a more complex taste in your brittle.

What should I do if my mixture doesn’t reach the right temperature?

If your mixture isn't reaching the desired temperature, make sure your stove is set to medium heat and that you're using a reliable candy thermometer. Stirring continuously will help distribute heat evenly. If it still doesn't work, consider increasing the heat slightly, but watch closely to prevent burning.

How can I tell when the brittle is fully cooled and ready to break?

The brittle is fully cooled and ready to break when it feels firm to the touch and has a hard texture. This usually takes about 30 minutes to an hour at room temperature. If it feels sticky or soft, give it more time to cool completely before attempting to break it into pieces.
