This is from Southern Sideboards. This is an old candy thats been around for a long time. It is too hot for kids to help with the cooking part. But when it cools they love to break it into pieces. I love the cinnamon.
Sprinkle powdered sugar on 2 (11 x 15 inch) cookie sheets.
Combine sugar, Karo and water in heavy saucepan and stir over medium heat until sugar dissolves. Continue to cook, without stirring, until syrup reaches 290 F on candy thermometer.
Remove from heat and add food coloring to desired intensity and the desired oil flavoring. I like the flavor a little stronger so I increase the amount of flavoring alittle more. (Be careful with the cinnamon and stand back when you add it or it will clear your sinus passages for you)
Pour onto cookie sheets,cool and break into small pieces. I just let it cool and whack it with the bottom of a bottle it shatters easily. This looks very pretty in jars for Christmas gifts and to set out. Not to mention it taste great!
