Remove dough from fridge 45–60 min before baking.
Preheat oven 45 min with stone/steel on lowest rack to hottest temp (ideally 550°F/287°C) + second steel 8–10" above.
Place dough ball on floured work surface, bottom side facing up. Flour dough, press and stretch into ~12" (34cm) round.
Place on semolina floured peel.
Assemble & bake (per pizza):
Spread ~200g/5oz (3/4c) sauce, leaving 1/2" rim.
Top with 175–200g mozz blend.
Stretch pizza out to edges of the peel.
Add pinch of flaky salt. Shimmy peel to check for sticking.
Launch onto bottom steel. Bake ~3 min, rotate 180, then 2–3 min more until browned, bubbly, slightly charred.
Cut into slices then re-heat individual slices on the bottom pizza steel for 90sec-2mins just before eating.
