  • Ingredients:
  • 1 cup water
  • 3 3/4 cup sugar
  • 1 1/4 cup light corn syrup
  • 1 tsp red food coloring
  • 1 tsp cinnamon oil (2 tsp. if you like it spicy)
  • 1 1/2 cup powdered sugar
  • 1 butter, for greasing the surface


  1. Butter a 15 inch x 10 inch x 1 inch sheet cake pan. Line the pan with parchment paper and butter the parchment paper, ensuring the edges are well buttered to prevent the candy from seeping underneath.
  2. In a large deep saucepan, combine water, sugar, corn syrup, and food coloring. Mix over medium-high heat until the sugar starts to dissolve. Attach a candy thermometer to the side of the pan, ensuring it does not touch the bottom of the pan for an accurate temperature. Continue to boil until the sugar mixture reaches 300°F (hard crack stage) – about 20 minutes. Watch closely; if the mixture starts to boil too close to the edge of the pan, remove the pan from heat, stir until bubbles subside, and then return to medium-high heat.
  3. Once the mixture reaches 300°F, remove the pan from heat and stir in the cinnamon oil, working quickly. Keep your face away from the mixture as it is strong like onions, and keep the work area well ventilated. Pour immediately into the prepared pan. Allow to cool for 4 hours.
  4. After 4 hours, dust the top of the candy with powdered sugar. Flip the candy over onto a large cutting board or cookie sheet and remove the parchment paper. Return the candy to the pan and use the tip of a sharp knife to break the candy into bite-size pieces. Dust with more powdered sugar and store in an airtight container.

Recipe Tips

  • Be cautious when working with hot sugar mixtures. Use a candy thermometer to ensure the mixture reaches the correct temperature for the perfect candy texture.
  • If you prefer a spicier flavor, increase the amount of cinnamon oil to 2 teaspoons.
  • Make sure to keep the work area well ventilated when adding the cinnamon oil to the hot sugar mixture, as the oil can have a strong aroma.
