Recipe: Cinnamon Rock Candy
Ingredients
- 2 cups granulated sugar
- ½ cup light corn syrup
- ½ cup water
- 1 teaspoon cinnamon oil
- ½ teaspoon red food coloring (optional)
- Powdered sugar for coating
Step-by-Step Instructions
Step 1: Prepare Your Tools
- Grease a large baking sheet or line it with parchment paper.
- Have a candy thermometer, a heat-resistant spatula, and a wooden spoon ready.
- Sprinkle a light layer of powdered sugar over the baking sheet to prevent sticking.
Step 2: Combine Ingredients
- In a medium-sized heavy saucepan, combine the sugar, corn syrup, and water.
- Stir the mixture over medium heat until the sugar dissolves completely.
Step 3: Boil the Syrup
- Attach a candy thermometer to the side of the saucepan, ensuring it doesn’t touch the bottom.
- Increase the heat to medium-high and bring the mixture to a boil without stirring.
- Cook until the syrup reaches 300°F (hard crack stage), which takes about 10-15 minutes.
Step 4: Add Flavor and Color
- Once the syrup reaches 300°F, remove it from the heat.
- Quickly stir in the cinnamon oil and red food coloring, being careful of the steam (it’s very hot and can cause irritation).
Step 5: Pour and Cool
- Pour the hot candy mixture onto the prepared baking sheet. Tilt the pan gently to spread the candy evenly.
- Allow the candy to cool completely, which usually takes 30-60 minutes.
Step 6: Break into Pieces
- Once the candy is fully set, use a hammer, mallet, or the handle of a knife to break it into bite-sized pieces.
- Toss the pieces in powdered sugar to prevent them from sticking together.
Tips for Perfect Cinnamon Rock Candy
- Be Careful with the Cinnamon Oil: It’s highly concentrated and can irritate your skin or eyes. Measure it carefully and stir it in quickly.
- Use a Candy Thermometer: Accurate temperature is crucial for achieving the right texture.
- Work Quickly: Once the candy reaches the correct temperature, move fast to pour it before it hardens.
- Customize the Spice Level: Adjust the amount of cinnamon oil to suit your taste. Start with ½ teaspoon if you prefer a milder flavor.
- Store Properly: Keep the candy in an airtight container to prevent it from absorbing moisture.

Frequently Asked Questions
Q1: Can I use cinnamon extract instead of cinnamon oil?
A1: No, cinnamon extract won’t provide the same intensity of flavor. Cinnamon oil is much more concentrated and designed for candy making.
Q2: Can I use other flavors?
A2: Yes! Peppermint, orange, or anise oil are great alternatives. Adjust the amount based on the strength of the oil.
Q3: How long does this candy last?
A3: If stored in an airtight container at room temperature, the candy can last for up to 2 weeks.
Q4: Can I double the recipe?
A4: Yes, but use a larger saucepan and work quickly, as the candy sets fast.
Q5: What if I don’t have a candy thermometer?
A5: You can test the syrup by dropping a small amount into cold water—it should form hard, brittle threads when it’s ready.
