Coffee Jelly

Stir together gelatin and hot water in a small bowl until gelatin dissolves; pour into a saucepan. Stir in coffee and sugar, and bring to a boil over high heat.

Pour coffee mixture into a shallow, 9-inch square or 7x11-inch baking dish. Chill in the refrigerator until solidified, 6 to 7 hours.

Cut coffee jelly into cubes to serve.
