Mix the water, starter, and salt in a bowl. Then mix in everything else.
Cover and let rise for 18-24 hours.
Grease a bread pan. Knead the risen dough for a bit (kinda like pulling taffy) and then set in the bread pan. Then let it rise for a couple more hours.
Bake at 375°F for 50 minutes. Then take it out of the pan and let it cool for a few minutes.
It might be worth it to buy an electric knife, since sourdough has a hard crust that's difficult to slice through.
