Ingredients

Scale

  • 2 cups granulated sugar

  • 1 cup water

  • 1/2 teaspoon flavor extract (optional) – e.g., peppermint, lemon, vanilla

  • Food coloring (optional)

  • 6 wooden skewers or cotton strings

  • 6 mason jars or tall glasses

  • Extra sugar (for coating skewers)

  • Clothespins or clips (to hold skewers in place)

Instructions

  • Boil the Sugar Solution
    In a medium saucepan, bring 1 cup of water to a boil. Gradually stir in the 2 cups of sugar until completely dissolved. The mixture should look thick and glossy.

  • Add Flavor & Color (Optional)
    Remove from heat. Stir in any food coloring or flavor extract you’d like to use.

  • Prepare the Skewers
    Dip each skewer in the sugar solution, then roll it in dry sugar. Let them dry for 1 hour—this will help crystals form faster.

  • Pour Solution into Jars
    Carefully pour the sugar solution into each jar. Avoid disturbing the sediment.

  • Insert Skewers & Let It Sit
    Suspend the sugar-coated skewers in the jars using clothespins to keep them centered. Make sure they don’t touch the sides or bottom.

  • Wait & Watch
    Cover jars with a paper towel and leave undisturbed for 5–7 days. Crystals will begin to form and grow.

 

  • Remove & Dry
    Once crystals reach your desired size, remove the sticks and let them dry on parchment paper for 1 hour.
