Here is my recipe for Glass Candy for those of you who are interested.
2 cups sugar
2/3 cup light corn syrup
3/4 cup water
1 bottle of flavoring
Mix sugar, corn syrup and water together over medium heat until dissolved. Bring to a boil and place a candy thermometer in the mix. Add food coloring at 260 degrees. Do not mix in, the boiling process will mix it. Continue with boiling until 300 degrees. Remove from heat, after boiling ceases, add flavoring and stir in. Pour mix onto cookie sheet. Wait until it hardens and break candy in pieces. I use a butter knife or whatever you have to break it with.
