Ingredients
- 2 cups granulated sugar
- 1 cup water
- 1/2 cup light corn syrup
- 1 teaspoon flavoring extract (e.g., vanilla, peppermint, or lemon)
- Food coloring (optional)
- 8 wooden skewers or sticks
- 8 clothespins or clips
Instructions
- In a medium saucepan, combine sugar, water, and corn syrup. Stir over medium heat until sugar dissolves.
- Bring mixture to a boil without stirring. Insert a candy thermometer and cook until temperature reaches 300°F (hard crack stage).
- Remove from heat and let cool for 5 minutes. Stir in flavoring extract and food coloring if using.
- While mixture cools, prepare skewers by wetting them lightly and rolling in granulated sugar (this helps crystals form). Let dry.
- Pour the hot syrup into a heatproof glass measuring cup or jar. Allow to cool to about 200°F.
- Place the sugared skewers into the syrup, using clothespins to hold them upright and centered, not touching the sides or bottom.
- Let the syrup cool undisturbed at room temperature for 7-14 days until crystals form and grow on the skewers.
- Once crystals have formed to desired size, remove skewers and let drain on a wire rack. Store in an airtight container.
Tips
- Use a clean jar and avoid moving it during crystallization.
- For larger crystals, let sit longer; for smaller, check after 3-4 days.
- Add a few drops of food coloring for colored rock candy.
- Store in a cool, dry place to prevent stickiness.
