3 firm but ripe nectarines, halved, pitted
3 firm but ripe purple/black plums, halved, pitted
3 firm but ripe red plums, halved, pitted
6 metal skewers or thick wooden skewers soaked in water for 30 minutes
3 tablespoons sugar
Spray the grill rack with nonstick spray and prepare the barbecue (medium-high heat). Thread one piece of each fruit on each of six skewers so that the cut sides line up and lay flat. Sprinkle the sugar over the cut sides of the fruit. Let stand until the sugar dissolves, about 10 minutes.
Place the fruit skewers on the grill cut side down. Grill the fruit until it is heated through and caramelized, about five minutes. Transfer one fruit skewer to each plate and serve.
Note: Apricots and peaches work well in this recipe.
