Step 1: Prepare the Skewers
- Grease the Skewers: Lightly grease the wooden skewers or cotton string with vegetable oil to help the sugar crystals stick.
- Dip in Sugar: Roll the greased skewers or string in some extra granulated sugar to create an initial layer. This will help the crystals begin to form.
Step 2: Make the Sugar Syrup
- Combine Sugar and Water: In a heavy-bottomed saucepan, combine the 2 cups of granulated sugar and 1 cup of water. Stir over medium heat until the sugar is completely dissolved.
- Add Cream of Tartar: If using, add the cream of tartar to the mixture. It will help prevent crystallization on the pan’s sides and create smooth candy.
- Bring to a Boil: Increase the heat to high and bring the sugar-water mixture to a boil. You’ll need to monitor the temperature closely.
- Candy Thermometer: Insert a candy thermometer into the syrup and let it cook without stirring until it reaches 300°F (150°C). This is the hard crack stage, where the syrup will begin to solidify into rock candy. It’s essential to get the temperature right for the perfect crunch.
Step 3: Flavor and Color
- Add Cinnamon Extract: Once the syrup reaches 300°F, immediately remove the pan from the heat. Stir in 1/2 teaspoon of cinnamon extract (or cinnamon oil for a stronger flavor). The cinnamon oil will provide a bolder, more intense cinnamon flavor.
- Add Red Food Coloring (optional): Add a few drops of red food coloring if you want your rock candy to have that classic candy-store look. Stir well to combine.
Step 4: Pour the Syrup
- Prepare the Container: Place your prepared wooden skewers or string in a glass jar or tall container. The skewers should be able to hang vertically without touching the sides of the jar.
- Pour the Syrup: Carefully pour the hot cinnamon syrup into the jar, covering the skewers or string, but leaving a bit of space at the top for the syrup to cool.
Step 5: Let It Cool and Crystallize
- Allow to Cool: Let the jar sit undisturbed in a cool, dry place. Over the next 3-7 days, sugar crystals will begin to form on the skewers or string.
- Avoid Disturbance: Make sure the jar is kept in a stable position so the sugar crystals can grow evenly. The process can take anywhere from 3 days to a week, depending on the humidity and temperature of your environment.
Step 6: Check for Crystals
- Check the Crystals: After 3-7 days, check to see if the sugar has crystallized to your liking. You should have a solid coating of crystals on the skewers or string.
- Remove and Dry: Once you’re satisfied with the crystal growth, carefully remove the skewers or string from the jar. Allow the rock candy to dry completely on a cooling rack or place it on parchment paper to cool.
Step 7: Cut and Serve
- Break Into Pieces: Once your cinnamon rock candy is fully cooled and dried, break it into pieces or leave it on the skewers for a fun display.
- Store: If you’re not eating it immediately, store the candy in an airtight container to keep it from absorbing moisture and becoming sticky. It can last for up to a couple of weeks.
Tips for Success
- Use a Candy Thermometer: A candy thermometer is essential for making rock candy. It helps ensure you reach the correct temperature (300°F) for the hard crack stage.
- Don’t Stir Too Much: Once the syrup is boiling, avoid stirring too much. Stirring can introduce crystals into the syrup that may cause the candy to crystallize prematurely.
- Humidity is Key: Rock candy loves dry air! If it’s too humid in your area, the candy may not crystallize as well. If possible, make the candy on dry days for the best results.
- Add Other Flavors: While cinnamon is traditional, feel free to experiment with different flavors. You can try peppermint, orange, or vanilla extract for variety.
Variations to Try
- Different Colors: You can customize the candy by using different food coloring. Try a rainbow effect or classic red for a festive look.
- Larger Batches: If you’re making this for a crowd, simply double or triple the ingredients and use multiple jars to grow the crystals.
- Flavored Sugars: For a twist, use flavored sugars (such as vanilla or fruit-flavored sugars) as the base for your syrup to introduce unique flavors.
