To make, bring a large pot of water to boil. Cut a small “X” at the bottom of each peach. Gently place the peaches in the boiling water for about 45 seconds.
Carefully remove the peaches with a slotted spoon and place them directly in a water bath. Let the peaches cool for a few minutes and then peel the skin away.
On a lightly floured clean work surface, roll out one sheet of the puff pastry just enough to cover the bottom of the quarter sheet pan and up the sides a bit.
Roll out the second sheet of puff pastry on a lightly floured surface. Using a sharp knife or pizza cutter, cut the dough into 10 strips, each strip a little smaller than 1 inch.
Then, fold back the alternating strips (the ones you didn’t fold back before), lay another perpendicular strip, and unfold the original strips back over it.
