1 c. sugar
1 c. dark corn syrup
1 tbsp. vinegar
1 tbsp. baking soda

Combine sugar, corn syrup and vinegar in heavy saucepan. Cook over medium heat, stirring, until sugar dissolves. Continue cooking, without stirring, to 300 degrees, on candy thermometer, or until a little of the mixture, dropped in cold water becomes very brittle. Remove candy from heat. Quickly stir in soda; mix well.

Pour into lightly buttered 9 x 9 x 2 inch pan. Do not spread as candy will spread itself. Cool. Break into pieces. Yield: About 1 pound candy.
