Full Step-by-Step:

Step 3: Cool and Pour
- Cool Down: Let the syrup cool for about 10 minutes.
- Pour: Carefully pour the syrup into your prepared jar.
Step 4: Insert the Skewers
- Place the Skewers: Insert the sugar-coated wooden skewers into the jar, making sure they don’t touch the bottom.
Step 5: Waiting for Crystals
- Let It Sit: Cover the jar with a coffee filter or a paper towel to keep dust out and place it in a cool, dry area.
- Wait: Allow the rock candy to form for 7-14 days, checking periodically to see the growth of the crystals.
Step 6: Enjoy!
- Remove and Dry: Once you’re satisfied with the size, remove the skewers from the jar and let them dry before enjoying or packaging them.
Tips & Variations:
