Blueberry Turnovers

Turnovers are one of the most versatile pastries that you can make in any size, using virtually any fruit. These miniature turnovers are made from 4½-inch rounds of puff pastry. (Traditional turnovers are made from 6-inch rounds.) For the filling, the blueberries are cooked with sugar until the mixture is thick enough to hold its shape. If you want to use other berries for the filling, cook them in the same way.
