In a medium saucepan, combine the granulated sugar and water. Place it over medium heat and stir gently, ensuring that the sugar dissolves completely into the water.
Once the mixture has reached a smooth consistency, stop stirring and allow it to come to a boil. Let it simmer for approximately 8-10 minutes, enabling the syrup to thicken slightly and become syrupy.
After simmering, carefully remove the saucepan from the heat. Incorporate your chosen food coloring and flavor extract into the syrup, stirring gently to blend everything evenly.
Allow the syrup to cool for around 15 minutes. During this time, prepare your jars or containers by thoroughly cleaning them and ensuring they are completely dry before use.
Slowly pour the cooled syrup into each jar, filling them about halfway to allow room for the sugar crystals to form.
If using wooden skewers, dip one end of each skewer into the syrup, allowing a generous coating to form. Next, roll the coated end in granulated sugar, as this will help kickstart the crystallization process.
Carefully insert the skewers into the jars, ensuring that the sugared end is submerged in the syrup without touching the bottom of the jar. For string, tie one end to a pencil and balance the pencil across the top of the jar, letting the string hang into the syrup.
To keep your creation safe, cover the jars with a cloth to protect them from dust. Place them in a cool, undisturbed location where they won’t be disturbed.
After about 7-10 days, check back to find stunning sugar crystals forming on the skewer or string, creating your delightful candy!
Once the crystals have developed to your liking, gently remove the skewer or string from the jar. Allow it to dry fully before serving or presenting.
