San Francisco Style Sourdough
aka "Black Canyon Sourdough Bread"

San Francisco style sourdough bread is basically a French bread As a free form loaf made with a sourdough culture characteristic of San Francisco. Many people, especially those in San As a pan loaf Francisco, like to believe that this bread can be made no where other than San Francisco. However, the organisms in a San Francisco sourdough culture have been identified for a number of years, and the techniques are hardly a mystery.

The final proof that you can make San Francisco style sourdough bread outside of San Francisco was hammered home when "The La Brea Bakery" of Los Angeles bread was voted the best San Francisco sourdough bread by the food editors of the San Francisco Chronicle. The editors were upset enough by the results of this double blind tasting that they repeated it. With the same results.

When I was running my bakeries, I called this "Black Canyon Sourdough" and it was quite popular. I thought it was a San Francisco Style Sourdough bread, however reading Dr. Sugihara's papers has shown me it really isn't. When I redo the site, I'll redo this page and include an authentic San Francisco style sourdough bread recipe. Why do I keep typing "San Francisco style sourdough"? While I strongly feel that you can make an authentic San Francisco Sourdough style bread anywhere, I also feel that if it isn't made in San Francisco, it shouldn't be called a San Francisco Sourdough Bread, just as if it isn't made in a small region of France, that sparkling wine shouldn't be called Champagne. Words DO matter.

In any case, you can make this bread at home. The bread can be made in many shapes, depending on your desires and tastes. The more surface area your bread has, the faster it will go stale. A round loaf or pan loaf will last the best, with a baguette lasting the least well.

Unlike most San Francisco sourdough recipes I've seen, I use part whole wheat flour. It makes the bread more interesting in color, texture, and taste. This is a very simple bread. While it's not in the ingredient list below, the real main ingredient is time - it will take 12 to 15 hours to rise. Let's start with the ingredients for two 1.5 lb (680 gram) loaves:

Weight in Grams Volumetric Measurement Ingredient Baker's Percentage
550 grams 2 1/4 cups Water 64.8
170 grams 2/3 cup Active sourdough Starter at 100% hydration 20
730 grams 5 7/8 cups Bread Flour 85.38
120 grams 1 cup Whole Wheat Flour 14.62
17 grams 3 1/4 tsp Salt 2

If you are measuring by weight, which we strongly encourage, weigh the ingredients into your mixing bowl in the order given. Stir until well mixed. You may knead by hand or machine, as detailed below.

If you are measuring with cups, start by measuring the starter you'll need. Whisk the starter before measuring it, so you'll be measuring starter, not bubbles. Then whisk in the water, the whole wheat flour, and then the salt. Set aside the whisk, and get a wooden spoon. Add the 3/4 of the bread flour called for, about 4 cups, and stir it into the mixing bowl. Add more white bread flour a bit at a time, stirring as you go, until the dough is too stiff to mix by hand.

At this point, you may knead it by hand or machine. To knead by machine, read your mixer's instructions and follow them. For most mixers we find kneading for 5 minutes, letting the dough rest for 5 minutes, and then kneading for 5 minutes works well.

To knead by hand, pour the dough out onto your lightly floured kneading surface. Knead the dough for 5 minutes, cover it and it let rest for another 5 minutes. Then knead for 5 more minutes. At this point, it should be resilient, springy, and pass the windowpane test.

Once the bread is kneaded, let it rest for 30 minutes. Then divide the dough into two 770 gram dough balls. You may recall, from the top of this page, that we are making 680 gram loaves. The added weight is to allow for weight loss in baking. Loaves tend to lose about 10% of their weight in the oven, and my goal was to make a finished loaf that is close to 1 1/2 pounds. Now form the dough into batards, boules, or pan loaves. Cover the loaves and let them rise at room temperature until doubled in size, probably about 12 to 15 hours.

Once the loaves have doubled in size, it's time to preheat the oven to 375 degrees Fahrenheit. Once the oven is at the right temperature - I use a thermometer to be SURE the oven is at the right temperature - slash the loaves with a razor blade, slide them into the oven, and put some water into a pan at the bottom of the oven. Allow to bake 45 minutes, or until the inside of the bread reaches 190 F. (Note - my kitchen is at 7,703 feet above sea level, which changes how bread bakes. At sea level, you may want to shoot for 205 F or so.)

Remove from oven. If you used a bread pan, remove the bread from the bread pan. Now let the bread cool on wire racks before slicing - if your family will let you. I often vary this recipe by letting the bread rise once in a mixing bowl, punching it down, kneading it some more, and then forming loaves. The second rise takes about 1/2 as long as the first rise, and also adds to the flavor.
