Rock candy is sooo pretty, makes a great gift, tastes delicious, and can be the perfect science experiment to do with kids. They just love being able to check in on what they made to watch the crystals grow each day. On top of all this, it's super, super easy to do! I've got a tutorial lined up for you so look no further, the rock candy's on it's way.
Materials you will need:
- 2-3 cups of sugar
- 1 cup of water
- Skewers / candy sticks (wooden)
- A jar or glass
- A large saucepan
- Food coloring
- Candy flavoring
Please note! You can very easily multiply the recipe's yield (i.e. double, triple etc. if you want to make several different colors). So long as the sugar to water ratio is close 3:1, the rock candy will grow.
1- Combine equal parts of sugar and water in a saucepan and heat until all of the sugar is dissolved.
2- Then slowly add more sugar in small amounts so that it'll slowly dissolve in the water.
3- The water should start to look slightly cloudy: this is the goal. It means the sugar is dissolved and the perfect saturation has been reached. Essentially, you're making asaturatedsugar solution (a solution where no more sugar can dissolve at a particular temperature). The sugar to water ratio should be 3:1. You can then add candy flavoring if you wish and then continue to heat the water until it comes to a simmer.4- Take the sugar-water from the heat, and allow it to cool. While that's cooling, you can prepare your skewers or candy sticks. Cut the skewers to the size you want (in relation to the jars your using), then dip the skewers in water and roll them in sugar.
5-Once coated in sugar, allow the sticks to dry. While those are drying you may prep the jars you plan to use.
6-Once the sugar-water is cool enough, pour it into jars and add food coloring if you'd like to (do it, it's pretty!). Then, when the sticks are dry, place them in the jar(s).
You want to make sure the sugar coated sticks are completely dry before placing them in the jars. The rock candy uses the sugar to grow on, and if the sugar on the sticks isn't dry, it'll dissolve in the water. It's also very important that the sticks aren't touching the bottom or the sides of the jar.
And that's all you have to do! Now it's time to observe your jars (not in one day...).
This is what the candy started to look like after just one day:
And after 3 days:
And after one week look at these beauties!
You can totally leave your candy in the jars longer if you want to. Then once you're happy with the size of your candy, remove the sticks from the jars and place them on a plate to dry. Once they're dry, they're all yours. Enjoy!
