In a large bowl, mix the flour and water until well combined. Let it rest for 30 minutes.

Add the sourdough starter and salt, and mix until a dough forms.

Knead the dough for about 10 minutes until it is smooth and elastic.

Place the dough in a greased bowl, cover it, and let it rise for 4-6 hours, or until doubled in size.

Shape the dough into a loaf and place it in a bread pan.

Preheat the oven to 450°F (230°C) with a Dutch oven inside.

Score the top of the loaf with a bread lame for design.

Place the loaf in the Dutch oven and bake for 30 minutes with the lid on, then remove the lid and bake for an additional 15-20 minutes until golden brown.

Let it cool before slicing.
