Two nights before you want to make your bread combine the sourdough starter and lukewarm water mixing until totally combined. Add the flour and mix well.

Loosely cover and let sit for 12 hours or overnight.

In a large bowl add 1/4 cup of the active sourdough starter. Add in the warm water and stir untilt he starter has dissolved.

Add the all purpose flour to the yeast mixture, mixing to combine completely. Let the dough rest for
30 minutes.

Sprinkle the salt over the dough and mix to combine. Let the dough rest for 2 hours more.

Gently knead the dough for a minute then let the dough rest for 2 additional hours.

After 4 hours add the garlic and Parmesan cheese and knead until completely incorporated into the dough.

Work the dough by pulling the corners of the dough toward the center to form a ball. Once the ball is formed, turn it so the pulled edges are on the bottom of the dough.

Place the ball in a bowl, cover with a dish towel, put in
the refrigerator, and let rise over night.

Place a Dutch oven in the oven and preheat the oven to 450 degrees.

Turn the dough out onto a piece of parchment paper and sprinkle with flour.

Cut an X into the top of the dough.  Remove the Dutch oven from the oven and lift the dough into the pot using the parchment paper. 

Cover with a lid and bake for 30 minutes.   Remove the lid and bake for 10 additional minutes.  Remove from oven and cool.
