Preheat your oven to 220°C.
Peel and boil the potatoes. Put the dough on floured or oiled baking trays and stretch it across creating a rather thin base.
Cut the guanciale in strips.
Sprinkle the mozzarella cheese over the dough.
Drain the potatoes and slice finely. Arrange the slices evenly on the dough mixed with the guanciale. Top with the gruyère cheese and rosemary, drizzle some olive oil and season with salt and pepper.
Roast in the oven for approximately 15 – 20 minutes until the dough is starting to brown, as well as the potatoes – then your pizza will be ready to come out.
If you want to make your own dough here are the instructions to make a simple pizza dough:
- 250 grams all-purpose or bread flour
- 1 1/4 teaspoons instant or active dry yeast
- 1/4 teaspoon fine sea or table salt
- 1/4 teaspoon granulated sugar
- 2/3 cups room temperature water
In a medium bowl, stir together the flour, yeast, salt, and sugar. Add the water and, using a wooden spoon or your hand, mix until well blended, about 30 seconds. Cover the bowl and let sit at room temperature until the dough has more than doubled in volume, about 2 hours.
