1. Run a knife around the centre of each nectarine. Twist firmly to separate and remove the stone.
2. Place the raspberries (reserving a few for decoration) in a food processor with the sugar a grated orange rind and the juice of the orange. Process until smooth and sieve to remove the seeds.
3. Tear four large pieces of foil. Place two nectarine halves on each piece and spoon over sauce. Wrap up loosely but securely. Barbecue over medium coals for 10-15 minutes.
4. Serve with a sprinkling of nuts and fresh fruit.
