Preheat the oven to 350 degrees F.
Roll out the puff pastry to a uniform thickness. Cut out 4 rounds about 7 inches across. Fit the puff pastry into the tart shells. Trim the excess pastry, line the tart shells with aluminum foil, and weight the pastry with pie weights or rice. Bake the shells until golden brown at the edges, about 15 minutes. Remove the weights and foil and bake until the bottom of the shells are dry, 3 to 5 minutes. Set the tarts aside to cool.
Reduce the oven temperature to 350 degrees F.
In a small bowl, combine the blueberries, sugar, and 1 tablespoon of brandy. Spoon the blueberries into the tart shells.
In a medium bowl, beat the eggs with the cream and the remaining brandy. Spoon the custard over the blueberries. (Keep in mind that the custard will expand slightly as it cooks so fill the shells to just below the crust edge.)
