Ingredients
  

For the Rock Candy
  • 1 cup water hot enough to dissolve sugar
  • 3 cups granulated sugar
  • wooden lollipop sticks clean and dry
  • popsicle sticks for suspending candy sticks
  • clothespins to attach lollipop sticks and suspend in jars
  • quart-size wide-mouth mason jars for sugar solution and crystal growth
  • few drops gel food coloring optional, for vibrant colors
  • few drops flavor extract optional, e.g. vanilla or peppermint

Equipment

  • Large Pot
  • Mason Jars
  • Wooden Lollipop Sticks
  • Popsicle Sticks
  • Clothespins

Method
 

  1. Step 1: Dip each wooden stick into water, then roll in granulated sugar to coat. Lay sticks flat and let dry completely to help crystals cling.
  2. Step 2: In a large pot over medium heat, combine 1 cup water and 3 cups sugar. Stir constantly until sugar dissolves and the mixture boils.
  3. Step 3: Remove pot from heat. Stir in gel food coloring and flavor extract if using, to customize your candy.
  4. Step 4: Let sugar solution cool for about 20 minutes to prevent sticks from cooking the sugar too quickly.
  5. Step 5: Pour cooled solution into mason jars, leaving space at the top to prevent overflow.
  6. Step 6: Lay a popsicle stick across each jar’s top. Attach a clothespin to a prepared lollipop stick and lower it into the jar, sugar-coated section submerged but not touching the bottom.
  7. Step 7: Place jars in a clean, undisturbed spot. Avoid moving or shaking for about 5 days while crystals grow.
  8. Step 8: After 5 days, gently break surface sugar film and carefully remove sticks. Loosen any crystals stuck to jar sides with a knife.
  9. Step 9: Transfer finished rock candy to clean jars or stand upright in a cup to dry completely before enjoying or gifting.

Notes

Rock candy is flexible: try different flavors like lemon or cinnamon, natural colorings, or coating candy with edible glitter or melted chocolate. Store in airtight containers in cool, dry places. Properly stored, rock candy lasts weeks to months.
