This recipe is yet another version of "classic San Francisco sourdough bread". By far, this has been the best, most flavorful recipe I've yet run across. This recipe makes one 1¾ pound, lean, white, San Francisco sourdough loaf. Read more about that here.
Leave at room temperature (70-80F) all day long.
Add these ingredients to the sponge created in the previous step.
Add about 1/2 the total final flour (about 1½ cups). Allow to rest for 30 minutes.
Dry mix the rest of the flour and the salt, and add to the sponge created previously.
Do 4-6 stretch & folds or flatten & folds with 15-min intervals. I do these on the counter, covering the dough with the inverted mixing bowl.
Oil the bowl. Turn the dough until coated, and allow to at least double at between 68°-85°F. Being on the cool side is fine—better in fact. While it will take longer to rise, cooler temps improve the flavor and texture of your bread. Check the dough every 30 minutes or so and when it is about 1½ - 2 times its original size, you’re ready for the next step.
When your dough has risen so that it’s lighter and doesn’t spring back when you poke it with a finger, it’s time to begin the shaping process. [I thought it was until it had risen 1-1/2 to 2 X?]
Gently, using your knuckles, flatten the dough. You don’t really want to punch it down. Just knocking out the biggest bubbles is enough. Dividing, if you do it, and/or shaping it will take care of getting rid of any excess bubbles. Let it rest, covered, for about 15 minutes or so.
For a round or oval shape, pick up the dough and gently pull the edges under, pinching firmly on the underside.
Cover and allow to rise in a warm (68°-85° F.) non-drafty place again. Since I always bake into a cold oven, I do this in the oven. It keeps the bread out of the way, and has the added benefit of having a light if the final rising temperature is cooler than I'd like. This should take from one to three hours, depending on the temperature, the characteristics of your culture, and your flour. Always expect—and allow for—your sourdough to rise much more slowly than breads built with commercial yeast.
When your unbaked loaf has risen to about 2 or more times its original size, it’s time to bake. Coupe if desired. Lightly mist if desired (for a thinner, crunchier crust). Turn on oven and Bake 400° F for 45-60 minutes. NB: if your loaf shows significant "oven-spring" it means that you could have let the final rise go on longer. The longer the rise, the better the taste.
The original author of this recipe says that she's discovered through trial and error that if you want REALLY active sourdough starter, you feed it with a volume of flour and water equal to or more than the volume of starter you're feeding--in other words, a really big meal for the little critters. And you keep doing this for two or three more feedings before making your dough. This REALLY active yeast produces bread that has a 'nice' crust (but not as thick and hard) and a softer center. And the bread doesn't taste as sour.
NB: On the other hand, if you make the volume of the last two or three feedings before you begin to make the dough only about half the volume of the starter you're feeding, then the resulting bread is much crustier and the interior of the bread has much more body—it's not soft at all. And the bread tastes more sour.
Another tip for making your sourdough more sour is to add about a tablespoon or two of plain rye flour to the sponge for each cup of flour you're using. It's important to remember that longer, slower, cooler proofing's and risings contribute heavily to that wonderful sourdough flavor.

The original process embodied in this recipe is from Ms. Linda Wilbourne, and can be found at: http://www.thewilbournegroup.com/Sourdough/SourdoughStarterHelp.htm. In addition to this recipe, she also sells some accoutrements and sourdough starter. So far, I have not baked with that starter...but plan to do so shortly—using this recipe—so that I may compare her starter with my current starters.
