Feed your starter 4-12 hours before you plan to use it.

In a medium bowl, combine the active starter with water, stirring well with a fork.

Add the flour and salt. Mix with a fork until the ingredients are combined. The dough will look rough and sticky, which is perfectly fine.

Let the dough rest for 10 minutes and then stir it one more time. There should be no dry spots and it should look like traditional bread dough.

After the initial rest, cover the bowl again and let the dough ferment for 8-18 hours at room temperature. This is the bulk rise, allowing the dough to develop flavor and structure. An overnight rise is generally the easiest timer for most bakers.

Gently transfer the dough onto a lightly floured surface. Shape the dough by tucking the edges into the center, forming a tight ball. Let the dough rest for 5-10 minutes.

Dust a proofing basket or an 8-inch mixing bowl (lined with a floured kitchen towel or generously coated with cooking spray and flour) to prevent sticking. Place the dough ball, smooth side down, into the basket or bowl. Cover with a damp towel.

Let the dough rest for 1-4 hours at room temperature until it spreads slightly and looks puffy.

Preheat your oven to 450°F (230°C). Carefully turn the dough out onto a piece of parchment paper, score the top, and transfer to a preheated Dutch oven with the lid on.

Bake covered for 40 minutes, then remove the lid and bake for another 10-15 minutes until dark brown and hollow-sounding when tapped.

Remove the bread from the oven, transfer to a wire rack, and let cool for at least 1 hour before slicing. Enjoy the bread fresh, or use leftovers for toast and sandwiches!
