Remove puff pastry from package and thaw according to package directions
Meanwhile, preheat oven to 400º
Peel and core apples
Dice into ¼ inch pieces
In a medium bowl, combine diced apples, sugar, flour cinnamon and extract
Stir to combine, making sure apples are evenly coated; set aside
On a lightly floured surface, roll each pastry sheet into a long rectangle, about 9x13 inches
Transfer each sheet to it's own baking sheet lined with parchment paper
Cut out a 2½ inch section from each rectangle, creating 4 'flaps'
With a small side facing you, cut ½ inch slits in large flaps, being sure each side has the same number of flaps; repeat with second pastry sheet
In a small bowl, create an egg wash by beating the egg and water together
Brush the pastry {both the center of it and the flaps} with the egg wash
Fill the center of the pastry with ½ of the filling, draining juice back into bowl from each spoonful as you go {this will help keep your braid from being too gooey}
Fold top flap over apples; repeat with bottom flap
Alternating sides, fold the strips of dough on the side flaps over your filling, overlapping them to create a braid
Brush top of braid with more egg wash
Repeat steps 12 -16 with second pastry sheet
Bake at 400º for 35 minutes, or until apples are soft and pastry is golden
In a small bowl, combine sugar and milk until smooth
Drizzle over warm apple pie pastry braid
Serve warm
How much liquid is too much when enclosing fresh fruit inside delicate laminated dough? Managing moisture is the primary challenge when baking sliced apples within puff pastry, because excess juices will prevent the butter layers from expanding properly. Selecting firm-fleshed fruit varieties like Granny Smith or Gala ensures the interior maintains structural integrity during baking rather than collapsing into a puree. Dicing the fruit uniformly into quarter-inch pieces allows for even heat penetration, meaning every bite cooks at the exact same rate inside the oven chamber.
Shaping and Structuring the Pastry
Working with laminated dough requires cold temperatures to keep the butter solid between the flour layers. If the dough becomes sticky or pliable during the cutting process, transfer the baking sheet to the refrigerator for ten minutes before folding the side flaps. Draining the excess juices from the apple mixture before depositing it into the central channel protects the pastry from becoming soggy at the base. Alternating the overlapping strips across the top creates an insulated enclosure that traps steam gently, cooking the apples while rendering the exterior crisp.
Monitoring Doneness and Finishing
Baking at 400 degrees Fahrenheit requires careful observation of visual cues rather than relying on internal temperature probes. The pastry is finished when the butter has fully rendered, producing a deep golden-brown exterior and clearly defined layers along the braided edges. Letting the pastry cool for ten minutes on the parchment paper allows the interior starches to set before the final powdered sugar glaze is applied. Drizzling the milk and sugar mixture over a warm surface rather than a hot one prevents the glaze from melting entirely into a transparent syrup.
