1Add 450g of warm water (around 90°F/32°C) into a 6-quart high-sided lidded container.
2Add 7g of instant yeast to the water and stir to combine.
3Add 20g of sugar, 20g of olive oil, 15g of salt, and 680g of all-purpose flour to the mixture.
4Stir the ingredients with a sturdy spoon until the flour has absorbed most of the water and the dough forms a lumpy mass that can no longer be stirred.
5Wet your hand and finish mixing the dough by squeezing and bringing everything together until it's just hydrated flour.
6Cover the container with a lid and set it aside for 25 minutes at room temperature to allow for a short spurt of fermentation.
7After 25 minutes, the dough will have risen by about 50%, and the flour will look more hydrated.
8Place the covered container with the dough into the refrigerator to ferment overnight (or for 24 to 48 hours for best results).
9After overnight fermentation in the fridge, the dough will have risen about two and a half times and be full of gas bubbles.
10Flip the overnight dough onto a lightly floured surface.
11Pull the dough outwards left and right by about 6 inches to prepare it for shaping.
Starting with warm water (around 90°F/32°C) gets the fermentation off to a vigorous start and helps the yeast stay active in the fridge.
Dry active yeast can be used as a direct substitute for instant yeast, but instant yeast gets the fermentation started much faster.
For a quicker option, ferment the dough at room temperature for an additional 90 minutes after the initial 25-minute fermentation. Be warned, this dough will be weaker and have less flavor.
For best flavor and strength, ferment the dough in the fridge for 24 to 48 hours. It can be stored in the fridge for up to 7 days.
To shape the dough, gently pull it outwards from left to right on a lightly floured surface.
