Place a parchment paper over your baking tray and spread or roll out the puff pastry over the parchment paper.
1 Puff Pastry Sheet
Cut puff pastry into 6 same-sized rectangular.
Place a ham slice, a cheese slice over each puff pastry rectangular. Sprinkle some oregano or marjoram over that.
6 Slices Cheese, 6 Slices Ham, 2 Teaspoon Oregano Dried
Fold the ham a bit in if it's larger than the rectangular, and fold the dough from one end to another into a pocket.
Seal the ends by twisting the corner dough a bit in, bit by bit, along the complete end line. That way the ham and cheese are well sealed into the pocket and the cheese won't come out. (see video)
Cut lightly into the top of each pocket to make a design of your choosing.
Break an egg into a bowl and mix it up. This is your egg wash. Spread it over your puff pastry pockets with the help of a pastry brush.
1 Egg
Place the baking steet into the oven and bake your pockets at 350 Fahrenheit/ 180 Celsius for about 10-12 minutes or until they turn golden brown on top.
