Peanut Brittle

1 cup Karo light or dark corn syrup

1 cup sugar

¼ cup water

2 tablespoons Mazola or Nucoa margarine

1½ cups salted peanuts

1 teaspoon baking soda

Combine corn syrup, sugar, water and margarine in heavy 2-quart saucepan. Cook over medium heat, stirring constantly until sugar is dissolved and mixture comes to boil. Continue cooking without stirring until temperature reaches 280°F. or until a small amount of mixture dropped into very cold water separates into threads which are hard but not brittle. Gradually stir in salted peanuts so mixture continues to boil. Cook, stirring frequently, until temperature reaches 300°F. or until small amount of mixture dropped into very cold water separates into threads which are hard and brittle. Remove from heat. Add baking soda; blend quickly, but thoroughly. Immediately turn onto heavily greased baking sheet. Spread mixture evenly to edges of baking sheet with a greased metal spatula. Cool. Break into pieces. Makes 1½ pounds.
