Start by lining two cookie sheets with parchment paper, ensuring they are completely covered to prevent sticking.

In a small saucepan, combine sugar, corn syrup, and water. Use medium heat to cook the mixture while constantly stirring until it reaches a temperature of 305-310°F.

Once your sugar mixture reaches the desired temperature, remove the saucepan from the heat. Quickly stir in the black sesame seeds.

Immediately pour the sweet mixture onto the prepared parchment-lined cookie sheets. Use a spatula to gently spread the mixture to about 1/4 inch thickness.

Allow the candy to cool at room temperature for about 15-20 minutes. Switch your oven to broil and place the brittle under the broiler for 1-2 minutes.

After cooling completely, break the brittle into pieces of your desired size and store in an airtight container.
