Start by washing the grapes thoroughly and patting them dry.
Prepare a baking sheet lined with parchment paper.
In a bowl, combine flavored gelatin powder with sugar.
Melt the white chocolate in the microwave until smooth.
Dip each grape into the melted chocolate, allowing excess to drip off.
Roll the chocolate-coated grape in the gelatin-sugar mixture until fully covered.
Place the coated grapes on the prepared baking sheet.
Repeat with all grapes, ensuring they are evenly coated.
Refrigerate the grapes for about 30 minutes to set the chocolate.
Serve immediately or store in an airtight container.
