Instructions

1. Line a 13×18-inch baking sheet with parchment paper and lightly coat it with nonstick cooking spray to prevent sticking.
2. In a medium heavy-bottomed saucepan, combine sugar, corn syrup, water, and salt. Stir well and bring to a boil over medium heat.
3. Attach a candy thermometer to the side of the pan, ensuring it does not touch the bottom.
4. Once the mixture begins boiling (about 6–7 minutes), add the sliced butter and stir until fully melted and combined.
5. Continue cooking until the mixture reaches 280°F.
6. Stir in the peanuts and continue cooking.
7. Bring the mixture up to 300°F (hard crack stage), stirring as needed to prevent burning.
8. Remove from heat and quickly mix in the baking soda. The mixture will foam slightly.
9. Immediately pour onto the prepared baking sheet and spread evenly.
10. Allow to cool completely before breaking into pieces.
11. Store in an airtight container at room temperature.
