Pour the water into a measuring cup, add the yeast, and leave it until it's bloomed and formed a creamy frothy head, about 10 minutes.
Add the flour, salt and olive oil to a bowl and pour in the yeast.
Mix until it comes together into a dough, about 5 minutes. It will not be smooth.
Dust a large surface with flour and turn the dough onto it.
Kneed the dough by pressing the heels of your hands into the surface, pushing it away, then folding it and pulling it back. Rotate each time you kneed. Continue until the dough is smooth, 5 minutes.
Cut the dough into 4 pieces using the bench scraper, and wrap each piece in a separate ziploc bag and place it in the fridge.
Leave the dough in the fridge for 36 hours.
Remove the dough from the fridge 2 hours before you plan to use it.
Roll it into a tight ball and place it on a floured surface. Flour the top of the balls, and cover with cellophane and then a tea towel and put in a warm place.
