Pastry
Prep
Thaw out puff pastry for ~15–20 mins, until it’s pliable enough to unfold easily
Make the filling
Preheat an oven to 420°F
Make an egg wash
Line a sheet pan with parchment paper or a silicone mat
Production
Unfold the puff pastry sheet and cut into thirds with a pizza cutter along the seams
Cut those in half to create 6 rectangles
Separate the pastries from each other
Add filling to the middle of each pastry
For each pastry:
Brush the long edges with egg wash to help seal
Fold dough from each side over top of the filling
Flip it over so the seam is on the bottom
Crimp the open ends closed with a fork
Brush the pastries all over with egg wash
Move the pastries to the lined sheet
Bake until golden brown, around 15–20 minutes
Let cool on a wire rack
Notes
These are best enjoyed warm from the oven.
This amount of filling is perfect for 2 puff pastry sheets.
I usually use at least 70% dark chocolate.
Even better is chili flavored dark chocolate.
I like to let the puff pastry thaw on one of those pre-cut flat sheets of parchment paper from a restaurant supply store.
You can use it as a work surface for the egg wash steps, too, so cleanup is really easy.
I’ve also used a mortar and pestle when I didn’t have access to a food processor.
