The name literally means ‘a thousand leaves’, and refers to the many flaky layers of crisp puff pastry used to make this beautiful French pastry. Puff pastry is layered alternately, usually with whipped cream and raspberry or strawberry jam. The top is glazed with icing or dusted with icing sugar. Crème Pâtissiere is sometimes used instead of cream, with a thick fruit purée instead of jam and occasionally a Chocolate Glaze. Make your own puff pastry, or, if you prefer, use commercial frozen puff pastry.
