Prepare your work surface by lining two cookie sheets with parchment paper.

In a medium saucepan, combine sugar, corn syrup, and water. Stir well to ensure sugar is fully dissolved.

Bring the mixture to a simmer, stirring occasionally. Watch for the temperature to rise, aiming for 305-310°F.

Remove from heat and stir in black sesame seeds, coating them quickly before the mixture hardens.

Carefully pour the hot mixture onto the prepared cookie sheets and spread evenly to about 1/4 inch thickness.

Preheat your broiler and place the sheets about 6 inches from the heat source. Broil for about 1 minute.

Let the Black Mirror Candy cool completely at room temperature.

Break into pieces or shards once cooled.
