Most sourdough recipes call for high-quality, unbleached all-purpose or bread flour. I always recommend King Arthur Bread Flour, King Arthur All Purpose Flour ... This will prevent your dough to stick ...

As America’s oldest flour company, King Arthur Baking Co ... a less expensive way to bake a nice artisan loaf of bread. A boule of sourdough bread from a bakery can cost $6, $7, $8.
