2. 2
   Put the tomatoes, the salt and half of the olive oil in a wide pot, cover and cook over medium heat about 20 minutes, until the tomatoes soften and release their liquid.

3. 3
   Pass the tomatoes and their liquid through a food mill or sieve and return the purée to the pot: the skins and seeds stay behind.

   Cook uncovered about an hour at a lively simmer, stirring now and then, until the purée reduces by half.

   💡The paste burns easily as it dries: stir and scrape the bottom and edges, and once it is thick, don't walk away.
5. 5
   Preheat the oven to 110°C (230°F).

   Oven

   💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
6. 6
   Grease a wide baking dish with the rest of the olive oil and pour in the purée in a thin layer. Dry in the oven about 3 hours, stirring and scraping the edges every 30 minutes, until the paste is thick, sticky and brick red.

For the Dough base

1. 8
   Mix the flour, yeast, sugar and salt in a large bowl.

2. 9
   Add the lukewarm water and olive oil and Knead about 8 minutes, until the dough is smooth, pliable and doesn't stick to your hands.

   💡For yeast dough, use the windowpane test: a small piece stretches into a thin, translucent sheet without tearing, and that's the sign the kneading is done. Add flour only by the tablespoon, and only if the dough is still sticky after a few minutes: too much flour makes a tough dough.
3. 10
   Cover and Let rise about an hour in a warm place, until the dough doubles in size.

   💡Let rise in a warm, draft-free spot. The dough is ready when it has doubled, and a gentle finger press leaves a dent that fills back slowly; if it springs right back, wait longer.

To assemble

1. 11
   Preheat the oven to 200°C (390°F).

   Oven
2. 12
   Roll out the dough into two large rounds.

   💡Let the pizza dough rise for 24 hours in the fridge (a long cold rise) — the dough develops a deeper flavor and an airy texture with big bubbles.

   💡Roll from the center outward and give the dough a quarter turn between rolls: this keeps it even in thickness and stops it sticking to the counter. If it springs back, cover for 10–15 minutes and try again.
3. 13
   Spread the sauce on half of each round.
4. 14
   Scatter the mozzarella, white cheese, pepperoni and oregano over the top.
5. 15
   Fold the empty half over the filling and press the edges firmly to seal.

   💡Leave 2 cm clear at the edge of the filled half and don't overfill: that way the edges seal well and the filling doesn't escape during baking.
6. 16
   Brush with olive oil and bake 20–25 minutes, until the calzone is golden.
