Chausson aux Pomme are also known as French apple turnovers. They are made with puff pastry dough and a green apple filling similar to apple pie. We placed a spoon full of the filling onto one half and egg washed the edges. We folded them in half and scalloped the edges. When they were baking some of my Chausson aux Pomme opened up. This may have been because I over filled them or because I did not make the hole big enough to let the steam escape.
