To make the pizza dough, divide the water into 2 containers: 700 g in one and 80 g in the other.
Add the yeast and 700 g of the water to the bowl of the Ooni Halo Pro Spiral Mixer. Set the Halo Pro to mix for about 1 minute at 15% speed (90 rpm) to dissolve the yeast. (For timings throughout the dough recipe, we strongly recommend using the Halo Pro’s built-in timer. The mixer will automatically stop when the timer is complete and prevent overmixing.)
Carefully add all the flour to the bowl and mix for 7 minutes at 15% speed (90 rpm).
Add 40 g of the remaining 80 g water to the bowl and mix for 2 minutes at 15% speed (90 rpm). Sprinkle in the sea salt and mix for 1 minute more. Add the remaining 40 g water and mix for 4 minutes at 15% speed (90 rpm).
Set the timer for 10 minutes and let the dough rest in the bowl with the Splash Guard closed.
After resting, perform a final mix for 30 seconds at 15% speed (90 rpm). Turn off the Halo Pro.
Tilt the mixer head open and remove the Breaker Bar and Spiral Dough Hook attachments. Keep the bowl attached to the Halo Pro. Use the Ooni Bench Scraper to remove the dough and transfer it to a clean Ooni Pizza Dough Box or airtight container.
Let the dough proof for 18 to 20 hours at room temperature (60° to 68°F/16° to 20°C).
5 to 6 hours before making the pizzas, transfer the fermented dough to a lightly floured work surface. Using the Ooni Bench Scraper and the Ooni Dual Platform Digital Scales, divide the dough into 8 portions, each 250
