In a big bowl, put water and mix the salt until you cannot feel it anymore with your fingers

Genltly wet the yeast and scrub it with your hand to let it melt into the water

Start adding flour (please use Caputo flour or any other flour with high containt of protein, something around 13 g per 100 g will be good) while mixing and continue in the bowl until it becomes a mass hard enough to be tranferred on the table\

Mix the dough by stretching it and pushing it to the table. This facilitates the formation of gluten. Please mix the dough for around 20 min as this is the time needed for the gluten to be formed mechanically by this process. Please also fold it over and over to immagazinate air that will feed yeast bacteria for a better fermentation.

Now the dough should be smooth and elastic. Cut it in 200-250 g balls max and put them in a container where you lay a thin layer of olive oil (to not make the balls stick to the container). Put the cover and let them rest around 10 h at room temperature.
