Rinse cranberries in a colander, discarding any that have become soft. In a medium bowl, heat syrup in the microwave just until warm. (I think mine took 30-45 seconds.) If it is too hot, wait a few minutes--you don't want your cranberries to pop. Add cranberries to the syrup. Cool, cover, and let soak in the refrigerator overnight.
Drain cranberries in a colander; do not rinse. Place sugar in a large bowl or baking sheet. Add cranberries in 2 batches and roll around until lightly coated in sugar. Place on a baking sheet until dry, about 1 hour.
Assemble crackers with one slice of brie, a light layer of cranberry chutney, and 4 or 5 sugared cranberries. Garnish with fresh mint sprigs.
Serve immediately. The wetness from the cranberry sauce will start to creep up on the sugared cranberries, making them not so sparkly, so these are best assembled last minute.
Notes
*One 12-ounce package is 3 cups. I one-and-a-halved the recipe for the berries so we had some leftover to snack on.**I bought a can of whole cranberry sauce and blended it a little bit. You will have leftovers if you do this.Source: Yummy Mummy
