Ingredients
 

Main Ingredients

  • 1 cup granulated sugar
  • 0.5 cup light corn syrup
  • 1.25 cup raw shelled peanuts Unsalted is best for control
  • 1 tbsp unsalted butter Plus a little to grease the pan
  • 0.75 tsp pure vanilla extract
  • 0.75 tsp baking soda Fresh for best foam
  • 0.13 tsp fine salt A small pinch

Instructions

Preparation Steps

  • Line a baking sheet with parchment and lightly butter it. Set nearby with a heatproof spatula.
  • Combine sugar, corn syrup, and salt in a large microwave-safe glass bowl. Stir until the sugar looks moistened.
  • Microwave on High for about 3 minutes 30 seconds, until the syrup is bubbling vigorously.
  • Stir in the peanuts to coat. Microwave again for 2 to 3 minutes, until lightly amber and fragrant.
  • Add butter and vanilla carefully; stir until melted. Microwave 45 to 75 seconds, until deep golden and very fluid.
  • Sprinkle in baking soda and stir briskly. The mixture will foam and lighten in color.
  • Immediately pour onto the prepared pan. Tilt and gently spread thin with the spatula; work quickly.
  • Cool completely until hard, about 30 minutes. Break into pieces to serve.

Notes

Variation: Stir a pinch of cayenne or cinnamon into the baking soda for a sweet-heat twist. Storage: Keep brittle in an airtight container at room temperature with parchment between layers for up to 2 weeks.
