Slice up the chorizo and set aside.
Mix the natural yogurt, strong white bread flour, baking powder and fine sea salt together in a mixing bowl with a wooden spoon until it comes together as a dough.
Lightly flour a clean work surface then knead the dough together briefly for a minute or so. This isn’t a traditional bread recipe, so you don’t want to knead too much to develop the gluten in the flour.
Preheat the oven to 200C, fan 180C. Lightly dust a work surface with a little plain flour. Roll the pastry into a round, roughly 25-28cm wide. Slide the pastry onto a floured, flat baking sheet.
Dollop over the tomato passata. Dot with mozzarella, pepperoni and chorizo and cook in the centre of the oven for 18-20 minutes.
Peel the garlic and grate into a bowl and stir into the olive oil.
Remove from the oven and finish with some torn basil, salt and a grind of black pepper.
Just before serving, drizzle a little more oil over the pizza, slice up and serve.
