Ingredients
  

  • 2 cups granulated sugar
  • 1/2 cup water
  • 1 tbsp light corn syrup optional
  • Gel food coloring
  • Edible glitter or luster dust
  • Edible glue or corn syrup
  • Silicone molds
  • Clean paintbrush

Instructions
 

  • 1. Brush the inside of your silicone mold with edible glue. Add a pinch of sugar crystals as "seeds."
  • 2. In a pot, combine sugar, water, and corn syrup. Heat until sugar dissolves completely.
  • 3. Remove from heat and stir in gel food coloring.
  • 4. Pour syrup gently into the prepared mold.
  • 5. Let sit undisturbed for 24–48 hours to form crystals.
  • 6. Pour out excess syrup and let dry another 24 hours.
  • 7. Brush dried crystals with glitter or dust. Optionally, coat the back with melted chocolate.

Notes

Use jewel tones like purple or teal for realistic geode effect.
Let molds sit still to encourage even crystal growth.
Dry in a low-humidity area for best texture.
