2 to 3 teaspoons anise extract or 1 teaspoon anise oil
8 to 10 drops red food coloring
In a large heavy saucepan, combine the sugar, water and corn syrup. Bring to a boil over medium heat, stirring occasionally. Cover and cook for 3 minutes or until sugar is dissolved. Uncover; cook over medium heat, without stirring, until a candy thermometer reads 300° (hard-crack stage).
Remove from the heat; stir in extract and food coloring (if using anise oil, keep face away from mixture as the aroma will be very strong). Pour into a buttered 13-in. x 9-in. pan. When cooled slightly but not hardened, cut into 1-in. squares. Cool completely. Store in an airtight container.
