Colorful homemade rock candy on skewers.

Ingredients

Servings4

Yields 4 servings

  • (2 cups) granulated sugar
  • (1 cup) water
  • (1/2 cups) light corn syrup
  • (1/4 teaspoons) food coloring (optional)
  • (1/2 teaspoons) flavored extract (like vanilla or peppermint)
  • Wooden skewers or string
  • Glass jar or container

Instructions

  1. 1

    In a medium saucepan, combine 2 cups granulated sugar, 1 cup water, and 1/2 cup light corn syrup over medium heat.

  2. 2

    Stir the mixture until the sugar completely dissolves, then bring it to a boil without stirring.

  3. 3

    Once boiling, let the mixture cook for about 5 minutes or until it reaches 240°F (115 °C) on a candy thermometer.

  4. 4

    Remove the saucepan from heat and let it cool for a few minutes. If desired, add 1/4 teaspoon food coloring and 1/2 teaspoon flavored extract, stirring gently to combine.

  5. 5

    Prepare your skewers or string by dipping them in the sugar solution, then rolling them in granulated sugar to coat. This helps the crystals to form later.

  6. 6

    Place the skewers or string vertically in a glass jar or container, ensuring they do not touch the sides or bottom.

  7. 7

    Pour the sugar syrup into the jar, covering the skewers or string completely. Let it sit undisturbed at room temperature for about 5-7 days to allow crystals to form.

  8. 8

    After a week, carefully remove the skewers or string from the jar, and let them dry for a few hours before enjoying your homemade rock candy.
