I never knew one of my childhood favorites, rock candy was so easy to make at home. I always was so excited to find it at souvenir shops or gift shops when we'd go out of town as a kid.

It's now a favorite of my teenage daughter too and before making our own we'd always find it at our local TJ Maxx or Burlington.

In today's post you'll learn how to make rock candy on a stick at home! This is a tasty learning opportunity and the kids will absolutely love every step of this fun recipe.

Plan ahead, the crystals need anywhere from 3-10 days to grow. The longer you leave them in the jars, the larger the crystals are. 

This recipe makes three rock candy on a stick, but you can easily multiply the recipe to make more at a time. Just grab a few extra mason jars and some different colors and extracts to make each set unique.

These are great for parties, to give as gifts or for a sweet treat at home. Have fun and enjoy!

Recipe tips:

  • Jars will have sugar crystals growing on their sides and maybe even across the top, you can break this to get your rock candy out. Just be careful not to knock the crystals off of your sticks.
  • To clean the jars it might be easier to let them soak in hot water for a bit to loosen the crystals. 
  • Baker’s twine can be used in place of the wooden sticks if desired. To do this, tie a life saver to the end bottom of the string to act as a weight and place it into the sugar mixture instead of the stick. Please note that although this method does work, we have found that wooden sticks work better.

How to Make Rock Candy on a Stick

Ingredients

  • 3 cups granulated sugar
  • 1 cup water
  • food coloring (optional)
  • 1/2 teaspoon flavoring oil or extract (optional)

Instructions

  1. Add sugar and water to a pan and heat over high heat, stirring constantly until it reaches a rolling boil. Be careful not to boil it too long or the candy will start to harden. Keep Stirring!
  2. Remove from heat and keep stirring until all of the sugar granules have dissolved. The mixture will suddenly get clearer when this happens.
  3. Carefully pour hot sugar mixture into the jar and put in the refrigerator to cool. This usually takes 30 minutes to one hour. You don't want the mixture to be cold, just about room temperature.
  4. While your mixture is cooling, prepare your wooden skewers by getting them damp and rolling them in sugar. Once they have a coating of dry sugar on them, put them aside to dry. This sugar coating will give our sugar mixture something to attach itself to resulting in larger crystals.
  5. When they cool to near room temperature, remove the jars from the refrigerator. If you are adding flavoring or food coloring do that step now.
  6. Tie baker’s twine to your picks and dangle them into the liquid sugar mixture, try to keep them from touching the bottom or each other. Once you get the picks placed where you want them in the jar, hold their strings along the sides of the jar screw the top on to hold the strings in place.
  7. Set the jar aside somewhere where it won't be disturbed and wait 3 -10 days for the sugar crystals to grow, the longer you wait the larger the crystals will get.
  8. When the crystals grow to a good size, they are ready to dry. Tie two straws into an X and balance it on top of a clean jar. Carefully remove the rock candy sticks from their jars and tie their strings onto the straw X’s. Don’t let them touch each other, let them hang in the jar from the X until they are dry.
  9. Once they are dry they are ready to eat!
