Step 1

In a large mixing bowl or in the bowl of a stand mixer, combine the water, yeast and 2 cups of the all purpose flour. Mix with the paddle on low speed until it forms a thick batter. Cover the bowl and set aside for 30 minutes.

Step 2

If using a stand mixer, switch to the dough hook. Add the salt and the semolina flour and mix until the dough begins to form a ball around the hook. Add the remaining 1/4 cup of all purpose flour. If mixing by hand add the flour using a wooden spoon and/or a plastic bowl scraper. Knead the dough for 5 minutes until it is smooth and elastic.

Step 3

Place the dough into a lightly oiled bowl, turn once to coat the dough. Cover the bowl and set it aside at room temperature for 1 - 1 1/2 hours or until doubled in size. At this point you can cover the bowl tightly, refrigerate overnight and finish shaping and baking in the morning or continue to bake the same day.

Step 4

Use the semolina/all purpose mix to dust a proofing basket or wooden peel. Turn the dough out onto a lightly floured surface. Knead 4-5 times, then use your cupped hands to form the dough into a smooth ball and place the dough, smooth side down, into the proofing basket. If you don't have a proofing basket place the dough directly onto a sheet of parchment paper or on the wooden peel.

Step 5

Cover the dough and leave in a warm place until it's almost doubled in size and it springs back slowly when poked, about 1 hour depending on the room temperature and dough temperature. Meanwhile, preheat the oven to 425°F. Place a Dutch oven with a lid into the oven to preheat.

Step 6

If the loaf is in a proofing basket, place a sheet of parchment over the dough and gently flip it over. Use a single edge razor or very sharp knife to cut a 1/4" deep X or square across the top of the loaf. Remove the preheated pan from the oven and remove the lid. Use the parchment to lift the loaf into the Dutch oven. If you don't have a Dutch oven, slide the parchment paper onto a baking sheet or onto a preheated pizza stone.

Step 7

Replace the lid on the pot and slide it into the oven. Bake for 20 minutes. Remove the lid from the Dutch oven. The loaf should be well risen and just beginning to brown.

Step 8

Continue baking another 20 minutes until the loaf is nicely browned and beginning to crisp. Remove the pan from the oven. Use the parchment to lift the loaf out of the pan. Use the parchment to place the loaf directly onto the rack in the oven. Bake another 5-10 minutes until the loaf is deeply browned and very crisp. Total baking time is about 40-50 minutes. If you are baking directly on a pizza stone or sheet pan the baking time may be closer to 30 minutes.

Step 9

Cool completely on a wire rack before slicing.
