Prepare the setup:

• Line a baking sheet with parchment paper or a silicone mat.
• Have your food coloring and flavoring ready for quick addition.

Cook the candy syrup:

• In a medium saucepan, combine sugar, corn syrup, and water.
• Heat over medium heat, stirring gently until the sugar dissolves.
• Stop stirring and increase the heat slightly. Attach a candy thermometer to the pan and cook until the mixture reaches 300°F (hard crack stage).

Add flavor and color:

• Remove the saucepan from heat. Stir in the vanilla extract and a drop or two of food coloring if desired. Be careful, as the mixture will be very hot.

Shape the candy:

• Pour the hot syrup onto the prepared baking sheet. Spread it thinly and evenly with a spatula for crystal shards or use molds for shaped candies.
• Sprinkle edible glitter or luster dust over the candy for added sparkle.

Cool and break:

• Allow the candy to cool completely at room temperature.
• If making shards, break the candy into pieces with a hammer or knife.

Serve and store:

• Serve immediately or store in an airtight container for up to 2 weeks.
