Prepare the Dough: In a large mixing bowl, combine the bread flour, wholemeal flour, 20g sugar, dry yeast, and 570ml water. Start mixing by hand to form a dough. Just before turning it out onto your workbench, add the 30ml olive oil and 25g cooking salt. Knead briefly to distribute.
Knead and Ferment: Knead the dough on your workbench for 8-10 minutes, until you achieve a smooth texture. Place the dough back into the bowl, cover, and refrigerate for 48 hours for slow fermentation.
Prove the Dough: 3 hours before you're ready to bake, remove the dough from the fridge. Divide into 260g (9.2 oz) portions and roll into tight balls. Place them on a greased tray with a lid. Let them prove at room temperature for 2-3 hours.
Preheat the Oven: Preheat your oven to 400°C (752°F) at least an hour in advance to properly heat-soak it. Note: New York-style pizzas are baked at a lower temperature than Neapolitan-style pizzas.
Prepare the Sauce: For the sauce, blend the tinned tomatoes with 10g salt, 5g sugar, and dried oregano until smooth. Be careful not to over-blend and incorporate air into the sauce.
Assemble and Bake: Stretch the dough to fit your pizza peel or baking surface. Top with the tomato sauce, low-moisture mozzarella, and Parmesan cheese. Bake for 3-5 minutes, aiming for a crispy bottom and golden cheese topping.
