Whisk salt into flour in a large bowl.
Stir sugar into warm water to dissolve it.
Add yeast to warm water and give it a little stir with your finger. In 1-3 minutes it should bloom. You'll know it when you see it. If nothing happens in five minutes, your yeast is dead, and you need to start over with new yeast. See the video below for yeast that is blooming like crazy.
Add olive oil to yeast mixture.
Pour the water / sugar / yeast / oil mixture into the flour & salt.
Briskly stir with a spatula until a shaggy ball forms.
On a lightly floured work surface (I use my kitchen counter) knead the dough by hand for 10-12 minutes.
Weigh the dough ball, and then divide by three. Make the one big dough ball into three separate equal size dough balls.
Get three storage containers. There's only two in the photo, but you are using three. (I like Rubbermaid - pictured.) Pour some olive oil into each of the,. Rub it around the bottom, and just a little bit up the sides. Place one dough ball inside, roll it around in the oil, then cover. Place in refrigerator for at least two days. Three days is best. This is called a Cold Ferment.
