Bake for about 1 hour and 40 minutes or until a thermometer inserted in the centre of the cake reads 65 °C (150 °F). Remove the cake from the water bath and the aluminum foil. Let cool for about 1 hour. Cover and refrigerate for 6 to 8 hours or until completely chilled. Run a thin knife blade between the pan and the cake, and then unmould the cheesecake. If desired, serve with a fruit sauce, to taste, and berries.
