In this tutorial, we learn how to make rock candy with ease. First, add 2 cups of pure sugar to boiling water. After this, stir in flavoring and food coloring then stir the mixture until it's thick. After this, remove from heat and let it cool. Then, pour in cooled water to the mixture and dip a skewer into the mixture, then roll around in sugar and place back into the jar using a paperclip to hold it on the top. You should see rock candy form in around 2-3 hours. Let the skewer sit for longer depending on how big you want the rock candy to get and enjoy eating it when finished!
