I have always felt that puff pastry is rarely given its due. I always see it used as a part of a dessert (usually not a very good one), when in reality, it could be a dessert on its own. The lamination process, building alternating super-thin layers of butter and dough, make for a light as air, crispy-flaky-buttery pastry. I wouldn't serve it as a dessert per se, but surely as a major component to build a dessert around.
What I have done to puff for many years is to eggwash the puff then coat it in an even layer of sanding sugar, then bake it first in a very hot oven to give it an initial oven spring to separate all of the layers and to create pockets of air (created by the steam from the butter) between the thin layers of dough. Next, I drop the temperature to continue to bake the puff without burning it, and to ensure the interior layers are fully baked. Finally, I brush the puff with a thick simple syrup (or if you must, corn syrup), bake it for 7 minutes, flip it over, then bake it for 7 more minutes. The result, for me, is a perfect sweet pillow of puff. Imagine the possibilities.
Note: not a single factory made puff pastry can replicate the one that is hand made, even when they use butter.
