Mix starter, flour, water together until it barely comes together.

Wait 20 minutes while the flour hydrates.

Add salt, stretch and fold several times.

In 10+ minute intervals, continue to stretch and fold until the dough is smooth.

Let it rise for 1-2 hours, then form it into whatever shape you like.

Let it rise again, preheat oven and enamel dutch oven to 500°F.

Place dough on a sheet of parchment, and into the dutch oven. Score the surface with a razor blade, cover, and throw it into the oven.

After about 15 minutes, lower the oven temperature to 400°F. Bake until internal temperature reaches at least 180°F, then remove and cool for at least one hour.
