Classic Peanut Brittle

Instructions

1. 1

   Grease a baking sheet and set aside.

2. 2

   In a medium saucepan, combine the granulated sugar, light corn syrup, and water. Cook over medium heat, stirring constantly until the sugar is dissolved.

3. 3

   Continue cooking without stirring until the mixture reaches 300°F (150°C) on a candy thermometer, or until a small amount of syrup dropped into cold water forms hard, brittle threads.

4. 4

   Remove from heat and immediately stir in the unsalted peanuts, baking soda, salt, butter, and vanilla extract. The mixture will foam up.

5. 5

   Quickly pour the mixture onto the prepared baking sheet and spread it out as thinly as possible with a spatula.

6. 6

   Allow the brittle to cool completely, then break it into pieces and store in an airtight container.
