Ingredients

  • 2 cups granulated sugar
  • 1 cup water
  • 1/2 tsp food coloring a few drops
  • 1/2 tsp flavor extract optional

Instructions

  • Soak skewers in water overnight if using. If using string, tie to a pencil or stick and hang across the top of a jar so that string hangs into the jar.
  • In a saucepan, bring water to boil and add sugar. Continue stirring until it is fully dissolved.
  • Add color and flavor.
  • Allow the sugar to cool for a few minutes, then pour into prepared jar.
  • Place the jar in an undisturbed location. Crystals will begin to form over the next few days.
  • After about 7 days, remove the stick or string from the solution and allow the crystals to dry.
  • Enjoy!
