This stunning summer dessert is more relaxed than it looks. The cheesecake is baked without a messy water bath and can be made days in advance. To avoid cracks on the surface, make sure to turn off the oven when the cheesecake is just set around the edges and quite wiggly at the center. If your cheesecake does happen to crack while cooling, the blanket of jammy berries will cover up any imperfections. Use the juiciest, most vibrant berries you can find, as they are the true stars of the show. Substitute an equal amount of blackberries, raspberries or blueberries for the strawberries, if you like, and adjust the sugar to taste.
