How to Serve

Recipe Tips

  • Make cotton candy just before serving; it deflates if stored too long.
  • Use UV-reactive or neon sugar for glow effect—available at specialty stores or online.
  • Handle cotton candy gently; moisture will make it sticky.
  • For multi-colored cones, spin sugar threads in layers of different colors.

Variations

  • Rainbow Glow Cones: Layer multiple colors of cotton candy for a rainbow effect.
  • Flavored Glow Cones: Add flavored extracts like grape, cherry, or bubblegum.
  • Spooky Halloween: Use orange and black cotton candy with glowing sticks for eerie effect.
  • Mini Cones: Make small individual cones for party platters or dessert tables.

Freezing & Storage

  • Cotton candy is best served fresh; storing is not recommended as it will melt or harden.
  • If necessary, store in airtight bags for a few hours in a dry, cool place.
  • Do not refrigerate or freeze, as humidity will ruin texture.

Special Equipment Needed

  • Cotton candy machine
  • Candy thermometer
  • Paper or plastic cones
  • UV glow sticks (optional, for visual effect)
