This is a recipie I use and people request it every year. It's really yummy
1 1/2 tsp baking soda
1 tsp water
1 tsp vanillia
1 1/2 C Sugar
1 C Water
1 C light corn syrup
3 tbsp butter or margarine
1 pound shelled unroasted peanuts ( I use Spanish peanuts )
Butter 2 baking sheets each 15 1/2 X 12 inches, keep warm. Combine baking soda, 1 tsp water and vanilla. Set aside.
Combine sugar, 1 C water and corn syrup in a large saucepan. Cook over medium heat, stirring occasionally, to 240 on a candy thermometer (or until soft ball stage).
Stir in butter and peanuts. Cook stirring constantly to 300 on candy thermometer (hard ball stage). Careful so the mixture does not burn!
Immediately remove from heat, stir in baking soda mixture thoroughly. Pour candy mixture into each pan that has been kept warm, spread around and smooth (about 1/4 inch thick). Allow to cool and drop pan onto counter breaking it into pieces.
