Ingredients

  • 1 cup sugar
  • 1 cup raw peanuts
  • 1/2 cup Karo syrup
  • 1 tablespoon butter

Instructions

  1. Boil the sugar, raw peanuts, and Karo syrup to hard crack stage.
  2. Remove from fire.
  3. Add butter; stir until melted.
  4. Add baking soda and stir well.
  5. Spread on a buttered cookie sheet.
  6. As it cools, pull from sides until very thin.
  7. Cool and break into pieces.

Tips & Substitutions

To achieve the perfect crack stage, use a candy thermometer and aim for 300°F. If you don't have peanuts, almonds or cashews can make a delightful substitution. Keep stirring the mixture constantly to prevent burning. If the mixture hardens too quickly, you can gently reheat it on low heat to make it more pliable.

Serving Suggestions

Peanut brittle makes a fantastic standalone treat or a sweet addition to a dessert platter alongside other confections like Chocolate Ripple Divinity. For a fun twist, chop it into smaller pieces and sprinkle over ice cream or yogurt for added crunch. Pair it with coffee or tea for a delightful afternoon snack.

Storage & Reheating

Store leftover peanut brittle in an airtight container at room temperature for up to two weeks. To maintain its crunchiness, avoid refrigerating it as moisture can make it sticky. If you need to reheat it, place pieces in a single layer on a baking sheet in a 200°F oven for a few minutes to restore crispness.

Frequently Asked Questions

What should I do if my peanut brittle is too soft?

If your peanut brittle doesn't harden properly, it may not have reached the hard crack stage. You can try reheating the mixture, bringing it back to 300°F before pouring it out again. If it still doesn't set, you might need to start over with a new batch.

Can I use roasted peanuts instead of raw?

Yes, you can use roasted peanuts, but you'll want to add them later in the cooking process to prevent them from overcooking. Stir them in after removing the mixture from heat, then proceed with adding the butter and baking soda.

What can I do with broken pieces of peanut brittle?

Broken pieces of peanut brittle can be used in various ways. They make excellent toppings for ice cream or can be mixed into trail mix. You can also crush them and use them as a decorative garnish for cakes or cupcakes for added flavor and crunch.
