I borrowed this recipe from All Recipes
1 cup white sugar
1/2 cup light corn syrup
1/4 teaspoon salt
1/4 cup water
1 cup peanuts
2 tablespoons butter, softened
1 teaspoon baking soda
1.Grease a large cookie sheet. Set aside.
2.In a heavy 2 quart saucepan, over medium heat, bring to a boil sugar, corn syrup, salt, and water. Stir until sugar is dissolved. Stir in peanuts. Set candy thermometer in place, and continue cooking. Stir frequently until temperature reaches 300 degrees F (150 degrees C), or until a small amount of mixture dropped into very cold water separates into hard and brittle threads.
3.Remove from heat; immediately stir in butter and baking soda; pour at once onto cookie sheet. With 2 forks, lift and pull peanut mixture into rectangle about 14x12 inches; cool. Snap candy into pieces.
I use 2 cups of peanuts because I love peanuts :o). I roast the peanuts in a low temp oven, 250 degrees, on the pan that was pregreased. At about 200-220 degrees I put the peanuts in the boiling sugar. I also let the candy reach slightly higher than the recommended 300 degrees, usually about 305-310 degrees. Then I remove it from the heat and add the softened butter and baking soda. After stirring it vigorously I put the candy mixture on the warm pan, spreading it around with the spoon. I then pop it into the freezer until it is hardened and enjoy. To break the candy apart, I place a napkin or towel on the candy and hit it with a hammer to break it open.
