2In a medium saucepan, combine the chestnut puree and sugar over medium heat.
Stir the mixture continuously until the sugar is completely dissolved.
Add the coffee powder and mix well to incorporate the flavor evenly.
Gradually add the corn flour, stirring constantly to avoid lumps.
Continue to cook the mixture, stirring frequently, until it thickens and pulls away from the sides of the pan.
Remove the saucepan from the heat and let the mixture cool slightly.
Once cooled, shape the mixture into small balls or desired shapes.
Allow the sweets to set at room temperature or refrigerate until firm.
Serve and enjoy your Chestnut Coffee Sweets!
