Add white flour to large container or bowl.
Add warm water (90-100 F degrees).
Mix together until no dry flour remains and you have a rough dough.
Cover dough and set aside for 30 minutes to allow the flour to autolyze (absorb the moisture).
After 30 minutes, uncover the dough and sprinkle the top evenly with the sea salt and the yeast.
Pull outside edge of dough and fold over center, do this 4-6 times until yeast and salt are enclosed.
Using two fingers (like you are making the "OK" symbol) cut through the dough 3 times.
Pull outside edge of dough up, it will not stretch much at this point, and fold over center again, 4-6 times.
Repeat the last two steps two more times until the salt and yeast are evenly distributed.
Turn the dough over so the last folds you made are tucked under a loose ball. This dough will need to be folded 3-4 times over the next 1.5-2 hours.
Cover the dough and allow to rest for 10 minutes.
Uncover the dough and perform another fold by pulling the outside edge of the dough upwards, being careful not to tear the dough and folding over the center, 4-6 times.
Hint: Every time you fold this dough it will gain elasticity, strength and rise. Pull the dough up and over to achieve maximum stretch without tearing it, this builds the structure to hold the developing carbon dioxide gas.
Turn the dough over so the last folds you made are tucked under a loose ball.
Wait 30 minutes and perform the last two steps again. You will do this two more times for a total of four folds.
Hint: These folds can be done every 30 minutes or longer.
