    p In a food processor fitted with a steel blade, combine all theingredients until they form a solid mass that rises above the blade. You can add extra water by the tablespoon if the mass does not congeal within the first minute. Tiny pieces of butter should still be visible in the dough when it's done. Remove the dough from the bowl and work it quickly into a ball on a lightly floured surface. Cover with plastic wrap and refrigerate for at least half an hour.
    p After the dough has rested in the refrigerator, roll it out on a lightly floured surface until it forms a circle approximately 13" in diameter. Center the cirlce of dough in a 10-inch tart pan with a removeable bottom. Use your knuckles to make sure that the dough tucks neatly against the edge of the pan and run the rolling pin around the rim to remove the excess. Cover and refrigerate again for at least half an hour.

    p Spread the pastry cream over the bottom of the shell. Arrange the apple slices in a circle around the outer edge of the shell, making sure the slices overlap. When the outer circle is completed, make a smaller circle, overlapping about half of the outer circle. If there's room, make a third circle. Fill the hole in the center with pieces of a few slices—let them stand upright. Cover the tart with a circle of wax paper and bake for 25 minutes. Remove the wax paper and sprinkle the sugar over the apples. Bake uncovered for 5–10 minutes more, until the sugar melts.
    p Boil the currant jelly until it reduces by one-third. With a pastry brush, paint the top of the tart with the currant glaze. Allow time for the glaze to set before serving (10 minutes).
