2 c. sugar
1 c. light corn syrup
1/4 c. water
1 1/2 c. salted peanuts
3 tbsp. butter
1 tsp. vanilla
2 tsp. baking soda

Combine sugar, corn syrup and water in a 3 quart heavy saucepan; mix well. Cook over medium heat, stirring constantly, until sugar dissolves. Continue cooking, stirring frequently to prevent scorching until mixture reaches 285 degrees. Remove from heat at once. Stir in peanuts and butter and cook, stirring constantly with thermometer until mixture reaches 295 degrees. Remove from heat at once. Add vanilla and baking soda, stir to blend (work fast). Mixture will foam.

Pour onto well buttered marble slab or 2 large buttered baking sheets. Spread out as thin as possible with spatula. As soon as brittle is cool enough so that you can work with it (about 5 minutes), turn it over and pull to stretch as thin as possible. When cold, break in pieces. Makes about 2 pounds.
