Combine all the ingredients in a large mixing bowl or the bowl of a stand mixer. Mix and knead until a smooth, soft, somewhat sticky dough forms.
Cover the dough and allow to rise until puffy, about 2 hours.
Form the dough into a 12" log and place it on a parchment lined baking sheet. Cover and let rest for 90 minutes.
Preheat the oven to 350°F. Bake the bread for 22~24 minutes or until nicely browned.
Remove the bread from the oven and transfer to a wire rack. Let the bread cool on the wire overnight -- do not cover.
In the morning, preheat the oven to 200°F. Slice the bread into ½" slices and place them on an ungreased or parchment lined baking sheet. Bake for 1 hour.
Turn all the slices over and bake for another 1 hour or until the toasts are very dry and crisp.
Remove from the oven and cool completely. Store, well wrapped at room temperature.
