3 cups granulated sugar
1 1/2 cups water
1 cup light corn syrup
3 cups raw, unblanched peanuts
1 teaspoon baking soda
1/4 cup butter
1 teaspoon vanilla extract

In a 3-quart saucepan, stir together sugar, water and corn syrup. Cook, stirring constantly, until mixture comes to a boil. Continue cooking until mixture reaches 232 degrees F on a candy thermometer, or until it spins a two-inch thread when the spoon is raised.

Stir in peanuts. Continue boiling, stirring occasionally, until mixture reaches 300 degrees F or until a small amount of mixture separates into threads which are hard and brittle when dropped into very cold water. Remove from heat; stir in baking soda, butter and vanilla extract. Quickly pour into two greased jellyroll pans. As mixture begins to harden, pull until thin.
