This is a quick make ahead dessert using store bought frozen puff pastry sheets and a filling of apples and raisins. Start by thawing the pastry sheets, during this time make the filling by peeling and cutting the apples into half inch cubes, the tart Gravenstein apple are great for cooking.
Cook these in a saute pan with a little butter, raisins, brown sugar and Cinnamon till tender, Let cool to room temperature. Cut puff pastry into 6x4 inch rectangles, spoon filling onto half of the square and fold over, crimp the edges and cut slits on the top to allow steam to escape while baking. Brush with a beaten egg and sprinkle coarse raw brown sugar on top. Bake on sheet pan in a preheated 375F oven and bake for around 15-20 minutes or untill golden brown. Serve with vanilla ice cream while its still hot. Note any kind of fruit can be used in the filling.
