Pepperoni Filling Method:
- Dice the guanciale and toss in a medium saucepan with a drizzle of olive oil.
- Set to medium heat until crispy. Add sliced garlic and cook until toasted.
- Follow that with fresh cracked black pepper and chopped rosemary cooking for 10 seconds before adding tomato paste, and stir in. Add water to loosen and let simmer for 2 minutes.
- Once finished, add in sugar, season with salt to taste, and extra virgin olive oil and stir together until emulsified.
- For the cheese, mix together grated mozzarella and grated grana Padano cheese.
- Slice the pepperoni and salami.
- To assemble, roll the puff pastry out until 12x10 inches and ¼-inch thick. Cut into strips about 3.5-inches wide and 5-inches long. Brush the edges with egg wash.
- Add a layer of sauce followed by a layer of cheese and pepperoni. Add another layer of sauce and cheese. Brush another piece of dough with egg wash and lay on top. Gently but firmly seal the edges.
- Trim the edges and repeat with the remaining pieces.
- Place on a baking sheet lined with parchment paper. Cover with plastic wrap and chill for at least 15 minutes.
- Brush tops of the pastries with egg wash. Optionally poke a few holes on the top of the pastries.
