• Heat oven to 400 degrees F. Line two baking sheets with parchment paper. Make the egg wash by mixing together the egg yolk with milk or cream in a small bowl and set aside.
• Unfold one of the thawed puff pastry sheets on a lightly floured work surface. Sprinkle a little flour on your rolling pin as well. Roll the pastry sheet into a 12-inch square (use a ruler and measure). Cut into FOUR (6-inch) squares. Then cut each square in half, so that you’re left with 8 (3x6-inch) rectangles. Repeat with the remaining pastry sheet. Transfer pastry squares to the baking sheets. Work with 1 tray at a time and pop the other tray in the refrigerator to stay cold.
• Spread about 2 tablespoons of raspberry preserves evenly onto 4 of the rectangles (really, just use as much or as little as you want), leaving a border around the edge. Brush the edges with your egg wash. Cut the remaining 4 rectangles into even ½-inch strips, going lengthwise. These will be your mummy bandages. Place the strips however you like, leaving an opening where the mummy eyes will eventually be. Watch my video for tips! Use a fork to gently press down the strips to seal them. Lightly brush the strips with egg wash and sprinkle liberally with sanding sugar. Don’t forget the edges! Loosen the pastries from the parchment paper using a spatula, just to make sure the pastries aren’t stuck and have a chance to rise. Repeat with the other baking sheet (pop first baking sheet in the fridge to remain cold).
• Pop both baking sheets into the oven and bake for about 15-17 minutes, or until your mummies are puffed, crisped on the bottom, and lightly browned on top. Transfer your mummies to a baking rack to cool slightly, and then top with candy eyes. Serve warm or at room temperature.
  

TIPS: Keep fully cooled leftover hand pies in a container with a tight fitting lid in the refrigerator. Warm up in a toaster oven for a few minutes to make the pastry crisp again. I tried making these with strawberry jam before, and it doesn’t come out as good. I think the raspberry preserves really makes them stand out in taste because it’s perfectly sweet and a little tart. These hand pies are yummy on their own, so feel free to make them without the eyes for any time of the year!
