In a medium saucepan over medium heat, combine sugar, corn syrup and vinegar. Cook, stirring, until sugar dissolves. Heat, without stirring, to 300 to 310°F (149 to 154°C), or until a small amount of syrup dropped into cold water forms hard, brittle threads. Remove from heat and stir in baking soda. Pour into prepared pan; do not spread. Mixture will not fill pan. Allow to cool completely.
