  • Candy Thermometer
  • Heavy bottomed pan


  • 1 ¼ cups light corn syrup
  • 1 cup water
  • 3 ¾ cups sugar
  • 1 tsp red liquid food coloring
  • 1 tsp cinnamon oil if using the .125fl oz it will be the entire bottle
  • cup confectioners' sugar
  • softened butter


  • Line a 15x10x1 inch pan with foil and butter the foil and set aside.
  • In a large heavy saucepan combine the corn syrup, water, sugar and food coloring.
  • Bring to a boil over medium heat, while stirring occasionally. Cover and cook for three minutes so all the sugar crystals will dissolve.
  • Uncover and cook on medium-high heat, without stirring, until a candy thermometer reaches 300° (hard-crack stage) about 25 minutes. Remove from the heat and carefully stir in the cinnamon oil.
  • Immediately pour into the prepared pan
  • Cool about 45 minutes
  • Break into pieces using a knife and a meat mallet. Bang the meat mallet against the knife, while pointing the knife into the candy. Dust the confectioners' sugar over the candy and gently toss to cover all sides.
  • Store in an airtight container.
