1. Dufour classic puff pastry is an excellent choice. (If you're using another brand, you may need more sheets of pastry to fill the baking pan.)
2. Line a 13" x 17 3/4" baking pan with parchment paper. Lay 2 sheets of dough (9" x 11" each) side by side on the pan. Press the dough into the edges of the pan and press the center where the 2 sheets overlap to make an even surface.
4. Prick the bottom of the pastry with a fork.
5. Place a piece of parchment paper on top of the pastry and scatter dried beans over it, covering the parchment completely. Bake pastry according to recipe instructions.
