Blueberry Puff Pastry Diamonds

Instructions

1. Preheat the oven to 400ºF. Line two baking sheets with parchment paper. Set them aside.
2. Cut the puff pastry sheet into nine equal squares. Working with one puff pastry square at a time, using a sharp paring knife, cut a half inch border around two of the sides of the square. Do the same on the other side, making sure to not connect the two incisions. Place 1 tablespoon of the blueberry jam in the center of the pastry. Pull one of the interior corners over the filling. Take the opposite corner and pull it over the filling as well. Pull the opposite exterior corner over the filling and repeat with the remaining corner. Transfer the pastry to the baking sheet. Repeat this process until all of the squares have been filled. Brush each pastry with the egg wash.
3. Bake the pastries until they are golden, about 17 to 20 minutes.
4. Serve them immediately as is or dusted with the icing sugar.
