Cinnamon Rock Candy

Directions

1. 1
   Line a 15x10x1-in. pan with foil; butter the foil and set aside. In a large heavy saucepan, combine water, sugar, corn syrup and food coloring. Bring to a boil over medium heat, stirring occasionally. Cover and cook for 3 minutes to dissolve sugar crystals.
2. 2
   Uncover; cook on medium-high heat, without stirring, until a candy thermometer reads 300° (hard-crack stage), about 25 minutes. Remove from the heat; stir in cinnamon oil (keep face away from mixture as oil is very strong). Immediately pour onto prepared pan. Cool completely, about 45 minutes.
3. 3
   Break the candy into pieces using the edge of a metal mallet. Sprinkle both sides of candy with confectioners' sugar. Store in airtight container.
