1 ⅔cups (350 grams)filtered or spring water(about 100ºF or baby bottle warm)
4 ¼cups (500 grams)bread flour(can substitute with all purpose flour)
2teaspoons (9 grams)fine salt(I prefer sea salt)
Instructions
In a large bowl, add the sourdough starter. Add in water and use a dough whisk or a wooden spoon to stir until dissolved. Stir in the flour and salt until a shaggy looking dough forms. Finish mixing dough by hand in the bowl until all the flour has been absorbed. Cover the bowl with a clean, damp kitchen towel and let the dough rest for 30-45 minutes.
Lightly flour your countertop. Pull the dough from the bowl with a dough scraper or by hand onto the countertop. Stretch and fold the dough for 15 seconds (see video below): grab the edge of the dough and bring it straight up it about 4 inches and tuck it into the center of the dough. Then, turn the dough 1/4 a turn. Continue this process until the dough has come full circle and it has tightened. Return the dough to the bowl, cover with a damp towel (or plastic wrap if you live in a dry area). Let rise overnight for at least 10 hours at room temperature or a warm location (72º and 80ºF degrees to ferment). Do not refrigerate the dough. The dough should double in size and look bubbly on the surface and under the dough when fermented.
In the morning, lightly flour your counter-top. Pull the dough from the bowl and shape the dough by stretching and folding it again. Let the dough rest 10 - 15 minutes. Line a medium sized bowl with a towel, or use a banneton bowl with linen cover (see photos), and dust heavily with flour. Let dough rise in it for 45-60 minutes.
Preheat your oven to 450ºF. Do not add your Dutch oven or baking pot, it does not get preheated. Cover the dough bowl with a long piece of parchment paper, about 20 inches long, and turn it over onto the countertop (see video). Slash the top of the loaf with a lame or sharp serrated knife. Gently lower the parchment paper dough into a heavy pot with a tight-fitting lid. NOTE: If using a pot with a dark interior cast iron pot, I recommend insulating the bottom with a round silicone sheet underneath the parchment paper. You can also place the Dutch Oven pot on a baking sheet. This helps the bottom crust of the bread from getting too dark in color.
Place the covered pot in the the oven and bake the bread covered for 30 minutes. Remove the lid and bake 20 minutes. Using oven mitts, carefully remove the bread from the pot. Bake it directly on the oven rack for 5-10 minutes to crisp the exterior (if needed). To ensure your bread is cooked through you can check the internal temperature. It should be 195ºF to 205ºF.

Notes
Let cool for at least one hour before cutting. Store sourdough bread at room temperature in a bag for up to 5 days.Can I make sourdough bread without a cast iron dutch oven? Yes, a heavy oven-safe pot with a lid will work. Use one that is about 9" to 10" in diameter and 6" high.This sourdough recipe was adapted from the Everyday Sourdough recipe in Artisan Sourdough Made Simple by Emilie Raffa.
