Preheat the oven to 400 degrees F. Peel and chop the apples into ¼ inch cubes. Mix the apple cubes with the raisins, orange zest, orange juice, brown sugar, flour, garam masala, curry powder, and salt.
Cut each puff pastry sheet into 9 squares and place them on baking stones or parchment paper-lined cookie sheets. Gently roll out each square into a diamond shape. Top each diamond with a tablespoon of apple mixture.
Whisk the egg with 1 tablespoon of water and brush the egg wash over the edges of the diamond. Then fold the dough over the apple mixture and crimp the edges with a fork.
Brush the tops with egg wash and sprinkle with Turbinado sugar. Bake for 17-20 minutes until golden brown on top. Serve warm or at room temperature.
