Stir the yeast into warm water and let it dissolve.
Measure out the flour into a large mixing bowl.
Add the dissolved yeast, salt, and tepid water to the flour and mix to form a rough dough.
Knead the dough for 2 to 3 minutes, then let it rest for 4 minutes and knead for one more minute.
Cover the dough with plastic wrap and let it rise for 3 to 5 hours at about 70º F.
Deflate the dough and fold it over itself, then let it rise for another 1½ to 2 hours.
Shape the dough into the desired form and let it rise for a third time for 1½ to 2½ hours.
Preheat the oven to 450º F.
Flip the dough, slash the top, and moisten with cold water.
Bake for 25 minutes, giving it a cold water wash every three minutes.
Let the bread cool for 2 to 3 hours before slicing.
