Step 1

Line a baking sheet with parchment paper or foil. Sift powdered sugar generously over the sheet.

Step 2

In a heavy-bottomed saucepan, stir the sugar, corn syrup, and water over medium heat until the sugar dissolves.

Step 3

Insert a candy thermometer into the saucepan and stop stirring. Bring to a light boil, without stirring, 15 minutes, or until it reaches 300°F or the hard crack stage. To check if it's done, drop a spoonful into ice cold water and it should harden.

Step 4

Remove the saucepan from the heat and let cool 1 minute. Stir in the desired amount of flavor and food coloring 1 minute, or until combined.

Step 5

Carefully pour the hot candy onto the lined baking sheet. Use a rubber spatula to spread it out evenly. Cool slightly, then sift powdered sugar over the top.

Step 6

While still soft, use a large knife to score 1-inch squares across the candy (this will help it break easier). Let the candy cool and harden for at least 1 hour, or until it's completely set and at room temperature.

Step 7

Once completely cooled and hardened, break into pieces. You can also use a hammer or mallet to break it into smaller shards, if desired.
