I find many cheesecakes too dense, but not this exceptionally light, summery version. The balsamic vinegar enhances the flavour of the strawberries wonderfully.
Preheat the oven to 170°C/fan 160°C/340°F/gas mark 3½. Butter very well the base and sides of a 23cm diameter, 7.5cm deep, round springform tin, making sure the flat side of the springform base is uppermost (the lipped side makes it hard to remove the cheesecake).
