Remove the puff pastry from the freeze and allow it to thaw. Do not thaw it fully, it should still be cold but pliable enough to unfold with the pastry sheet cracking.
Preheat the oven to 400°F and line two large baking sheet with parchment paper.
Lightly flour your workspace and roll out the puff pastry sheet into a rectangle, about 9x11 inches in size.
Using a sharp knife or pizza cutter, cut the sheet into 6 even sized rectangles, or 9 smaller squares. Repeat with the second sheet, getting a total of 12 pastries.
With a knife, gently score a border about ¼ inch in from the edges of each rectangle. Do not cut all the way through—this border will help create a raised edge during baking.
Add the pastries to the prepared baking sheets, spacing apart.
Bake at 400°F for 10-12 minutes, or until puffed and golden brown. Remove from the oven and allow the pastries to cool.
Once the pastries are fully cooled, gently run a knife along the scored border again, be sure not to cut all the way through.
Then, using the back of a spoon, gently press down the center of each pastry to create a shallow well for the filling.
