Mix 799g King Arthur AP flour, 20g salt, 2g instant yeast, and 11.2g sugar in a large bowl.
Add 496g cold water and 16g vegetable oil.
Use a silicone spatula to combine until very little flour remains in the bowl.
Dump dough onto work surface and knead for 10 minutes without adding flour.If sticky, let rest 5 minutes then continue kneading. Return dough to bowl, cover with damp cloth, and rest 30 minutes.
Divide dough into 3 equal balls of approximately ~438g each. OR take your dough ball, weigh it, divide by 3. Form balls by pulling dough into itself in your palm to create surface tension, then pinch bottom closed.
Grease a large container with oil and place dough balls inside.
Cold ferment in refrigerator for 3 days.
Remove from fridge 3-4 hours before baking and leave covered on counter to reach room temperature.
For sauce: Combine 1 can crushed tomatoes, 1 tbsp sugar, 1 tsp salt, and 1 tsp oregano. Blend with immersion blender for 12 seconds. Let oregano hydrate 15 minutes - taste and determine if you need 1 tsp more for your liking. I use 1 tsp. Preheat oven to 550F with convection setting if available.Place baking steel on center rack and preheat for 45-60 minutes. Dust work surface and dough ball with AP flour.Remember, the top of the dough ball is ALWAYS the top. Use bench scraper to lift dough ball, maintaining circular shape.
Press out crust edges first, then press center, repeating until palm-sized or larger.Flip and repeat pressing motion.Flip back so top side is up. Place dough on knuckles and stretch to ~14 inches, holding up to light to check for thin spots.
Spread 2-3 pinches of semolina flour evenly on peel.
Place stretched dough on semolina.
Spread 6 oz sauce evenly, leaving crust edge.
Spread 2-3 handfuls shredded mozzarella evenly over sauce.
Test that dough slides on peel using a shimmy motion; add semolina to any snag spots if needed.
Open oven, tilt peel slightly at back, and glide pizza onto steel.
Bake 3 minutes, then rotate 180 degrees with large spatula.
Bake another 3 minutes until cheese is melted and crust is golden brown, approximately 6-8 minutes total.I prefer my pizza to be well done - that's ~8 minutes in my oven. Cool on wire rack for 2-3 minutes before slicing.
