Jimmy Carter's Peanut Brittle

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.
