Bring the cheesecake to room temperature about 30 mins before serving. If using a loose-bottomed tin, unmould by placing on top of a can, then gradually pull down the sides of the tin. Slip the cheesecake onto a serving plate, removing the lining paper and base. Scatter the remaining raspberries and peach chunks over the cheesecake, dribble over some of the sauce and serve the rest alongside.
