This is very addictive. A perfect treat that melts in your mouth.MMMMMM...
granulated sugar, or brown sugar
dark corn syrup (i use karo)
apple cider vinegar
1Combine sugar,syrup and vinegar in a large deep saucepan over medium heat, stirring until sugar dissolves. Then continue cooking WITHOUT stirring until 300^ on candy thermometer. Remove quickly and stir in soda(it will foam up high), mix well and pour right away into a buttered 9x13-inch baking pan. Or spread out on buttered jelly roll pan. This pan is easier to score. When cool; break into large pieces.
If you desire you can spread 1 cup of chocolate chips, white chips, butterscotch chips or mint chips on the hot candy in the pan and spread to coat the top and sprinkle with nuts before it cools.
