Preheat your oven to 400°F and bring out your puff pastry to room temperature. Beat your egg with a fork and set aside.

On a baking sheet, lay on your parchment paper. Place a drizzle of olive oil followed by a drizzle of pomegranate molasses. Then place on your sliced shallots (I used 2 small slices of shallots per puff pastry), top with salt, pepper, sliced ham and finish with shredded gruyere cheese.

Place your puff pastry sheet on top, folding tight so ensure it is covered as best as you can. I'm using a fork here to fork down on the parchment, and then forking holes throughout the top part of the pastry - this will allow it to cook evenly and not swell up either. Repeat this step until you use up all your puff pastry.

Take a pastry brush and brush the tops of the puff pastry with your egg wash. Finish off with more shredded cheese on top.

Bake at 400 degrees for about 20-25 minutes until your pastry is cooked through and is looking golden brown. Remove from the oven and let cool for a couple of minutes, then flip over with a spatula. Serve on your favorite serving plate or board.
