🥘Ingredients

For the Candy

2 cups granulated sugar
1 cup water
1/2 teaspoon vanilla extract
Food coloring (optional)

👨‍🍳Directions

1Bring 1 cup of water to a boil in a saucepan over medium-high heat.
2Once boiling, gradually stir in 2 cups of granulated sugar, one spoonful at a time, until fully dissolved.
3The mixture should become clear and slightly thickened, with no visible sugar grains.
4Remove the saucepan from heat and stir in 1/2 teaspoon of vanilla extract and a few drops of food coloring if desired.
5Let the syrup cool for about 10 minutes until it is warm but not hot to the touch.
6Pour the syrup into clean glass jars or heatproof cups, filling each about halfway.
7For each jar, wet a wooden skewer or a piece of string, then roll it in a little granulated sugar to create a seed crystal.
8Let the coating dry for a few minutes.
9Place the sugared skewer or string into the jar, ensuring it does not touch the bottom or sides.
10Use a clothespin or clip to hold it in place.
11Cover the top loosely with a paper towel or plastic wrap to keep out dust.
12Set the jars in a cool, undisturbed spot and wait for crystals to form.
13After 3 to 4 days, you should see small crystals growing on the skewer or string.
14Continue for up to 7 days until the candy reaches your desired size.
15Once the crystals are large enough, carefully remove the skewer or string from the syrup.
16Place the rock candy on parchment paper to dry for a few hours before serving or storing in an airtight container.

One of the best things about this recipe is that it’s incredibly easy to customize – you can experiment with different flavors and colors to create unique variations. For example, you can try adding a few drops of peppermint extract for a refreshing twist or using natural food coloring for a more subtle hue.

When storing rock candy, make sure it’s kept away from direct sunlight and moisture to maintain its texture and appearance. If you need to reheat your rock candy for serving (for example if you’re using it as a topping for ice cream), simply place it in a low-temperature oven (around 200°F) for 5-10 minutes until it reaches your desired level of crispiness.
