Add 4 cups flour and sprinkle salt evenly over the top of dough. Knead dough on medium-low until most of the flour has been absorbed.
Turn mixer to medium speed and mix until dough is soft but no longer sticky about 5 minutes. If dough is sticky add an additional 1 tablespoon of flour at a time up to ¼ cup until dough is soft and smooth.
