Apple Turnover
Folded into triangles, these turnovers carry on a medieval European habit of baking fruit in pastry, and by the 17th century they were sold as hand-held snacks at French and English market stalls. The apples are cooked down in a pan first with butter, sugar and cinnamon, so they enter the oven already soft and jammy rather than raw and wet. Heat turns the moisture between the puff pastry layers into steam that pushes them apart, and the egg wash gives the top a lacquered, deep golden finish. The shattering crust is at its best in the first few minutes out of the oven.
