San Joaquin Sourdough

While I enjoy a variety of breads, the San Joaquin Sourdough remains my “go to” bread. It's easy to fit into a busy schedule. It uses few ingredients. It always tastes delicious. It's wonderful freshly baked but also makes great toast, French toast, garlic bread and croutons for salads or onion soup. It is almost as good after being frozen as fresh. What's not to like?

I first developed this formula about 3 years ago. Since then, I've tweaked the formula and methods in many ways. I know many TFL members have made this bread and enjoyed it. So, I thought an update on my current recipe might be of interest.

To summarize the changes I've made in the past 6 months:

  1. I substituted 25 g of whole wheat flour for an equal amount of the rye flour in the original formula. The difference in flavor is subtle, but I like it better.

  2. I adopted the oven steaming method for home ovens we were taught in the SFBI Artisan I and II workshops. 


556 g Bâtards

Prep time6 hours
Cooking time30 minutes
Total time6 hours, 30 minutes


450 g
all-purpose unbleached flour
25 g
Medium rye flour
360 g
10 g
100 g
Liquid levain (100% hydration)




In a large bowl, mix the active starter with the water to dissolve it. Add the flours and stir to form a shaggy mass. Cover tightly and let rest (autolyse) for 20-60 minutes.

Sprinkle the salt over the dough. Using a plastic scraper or silicon spatula, stretch and fold the dough 30 times, rotating the bowl 1/5 turn between each stroke. Cover tightly. Repeat this stretch and fold procedure 3 times more at 30 minute intervals.


After the last series of stretches and folds, scape the dough into a lightly oiled 2 quart/2 liter container and cover tightly. (I use a 2 quart glass measuring pitcher with a tightly fitting plastic lid manufactured by Anchor Glass.) Ferment at room temperature for 90 minutes with a stretch and fold after 45 and 90 minutes, then return the dough to the container and place it in the refrigerator and leave it there for 21 hours. 

Dividing and Shaping

Take the dough out of the refrigerator and scrape it gently onto a lightly floured work surface. Gently pat it into a rectangle. Divide the dough into two equal pieces.

To pre-shape for a bâtard, I now form a ball rather than a log. Place each piece of dough smooth side down. Pat into a rough circle, degassing the dough gently in the process. Bring the far edge to the middle and seal the seam. Then go around the dough, bringing about 1/5 of the dough to the middle and sealing it. Repeat until you have brought the entire circumference of the piece to the middle. Turn the piece over, and shape as a boule. Turn each ball seam side up onto a lightly floured part of your board.

Cover the dough with plastic wrap and/or a kitchen towel and let it rest for about 60 minutes. (The time will depend on ambient temperature and how active your starter is. The dough should have risen slightly, but not much.)

To shape a bâtard, I now favor the method portrayed in the King Arthur Flour instructional video. I encourage you to watch the video, but here is a verbal description of the method:

  1. For each piece of dough, place it in front of you on an un-floured board.

  2. Hold down the near side and stretch the far side of the piece into a rough rectangle about 8 inches front to back.

  3. Now, fold the far end two thirds of the way to the near end and seal the seam with the heel of your hand.

  4. Take each of the far corners of the piece and fold them to the middle of the near side of your first fold. Seal the seams.

  5. Now, the far end of the dough piece should be roughly triangular with the apex pointing away from you. Grasp the apex of the triangle and bring it all the way to the near edge of the dough piece. Seal the resulting seam along the entire width of the loaf.

  6. Turn the loaf seam side up and pinch the seam closed, if there are any gaps.

  7. Turn the loaf seam side down. Then, with the palms of both hands resting softly on the loaf, roll it back and forth to shape a bâtard. Start with both hands in the middle of the loaf and move them outward as you roll the loaf, slightly increasing the pressure as you move outward, so the bâtard ends up with the middle highest and the ends pointed .

Preheating the oven

One hour before baking, place a baking stone on the middle rack and put your steaming apparatus of choice in place. (I currently use a 7 inch cast iron skillet filled with lava rocks.) Heat the oven to 500F.


After shaping the loaves, transfer them to a linen couche, seam side up. Cover the loaves with a fold of the linen. Proof until the loaves have expanded to about 1-1/2 times their original size. (30-45 minutes) Test readiness for baking using “the poke test.” Do not over-proof, if you want good oven-spring and bloom!


Pre-steam the oven, if desired.

Transfer the loaves to a peel. (Remember you proofed them seam side up. If using a transfer peel, turn the loaves over on the couch before rolling them onto the transfer peel. That way, the loaves will be seam side down on the peel.) Score the loaves. (For a bâtard, hold the blade at about a 30 degree angle to the surface of the loaf. Make one swift end-to-end cut, about 1/2 inch deep.)

Transfer the loaves to the baking stone. Steam the oven. (I place a perforated pie tin with about 12 ice cubes in it on top of the pre-heated lava rocks.) Turn the oven down to 460F.

After 12-15 minutes, remove your steaming apparatus from the oven. Rotate the loaf 180 degrees, if it is browning unevenly. Close the oven door. (If you have a convection oven, switch to convection bake, and turn the temperature down to 435ºF.)

Bake for another 12-15 minutes, then remove the loaf and place on a cooling rack. Check for doneness. (Nice crust color. Internal temperature of at least 205F. Hollow sound when you thump the bottom of the loaf.) If necessary, return to loaf to the oven to bake longer.

When the loaves are done, turn off the oven but leave the loaves on the baking stone with the oven door ajar for another 7 minutes to dry the crust.


Cool on a rack for two hours before slicing.

beautiful.... shiny open crumb.

Why don't you bake it. I think you would like it.

...this bread looks SO perfect, and a little dangerous, I might add! :) I'd love to have that super-pointy end, it looks very crunchy.

David, I made your San Joaquin baguettes and they turned out so well, I was beyond thrilled. I need to put my post together, hopefully I'll find the time before the end of the semester. 

dmsnyder's picture

I'm so glad you enjoyed the SJSD baguettes! I'm looking forward to your post on your bake.


Mebake's picture

And boy was i impressed, the crust was crunchy, and sweet, and the crumb was soft and nutty. It very faintly sour, if at all.

Excellent all around bread, no wonder you always bake it.

Thanks for the formula , David!

I'm so happy you found the SJSD to your liking.

I have a batch of SJSD dough retarding myself to bake this afternoon.


daveklop's picture

my first batch of SJSD dough is resting in the fridge, to be baked some time tomorrow afternoon. A fun recipe to put together. I have one question and one observation:

My question: when you fold during the fermentation stage -- after you transfer it to the oiled container and just before it goes into the fridge -- do you do the full 30 folds or just a quick couple of folds?

My observation: making bread while doing other chores at the same time can lead to inattentiveness -- which is to say, I realized just now that I forgot to add the salt! I pulled the dough out of the fridge and kneaded it in, which will be an interesting variation on your recipe, to say the least. I'm curious to see what the effect of adding salt so late will be. And next time I'll pay closer attention to what I'm doing!

dmsnyder's picture


The number of S&F's I do each time depends on the dough. The idea is to develop strength in the gluten and avoid tearing the developing gluten strands. So, if the dough gets stiff after 10 folds, let it be for another 30 minute rest. If it needs 30 folds to get to that point, do 30. 

With some experience with this technique, you will get a feel for when enough is enough.

With procedures like the ones used in the SJSD, I depend heavily on alarms. I use the one on my oven, the one on my microwave, I have two additional digital timers, not to mention the timer function in the clock app on my iPhone. It is not that unusual for me to have 3 alarms set at once for different things I or my wife and I are making. The virtue of the digital alarms is that you can literally put them on top of the covered dough, so when it goes off you know which recipe it's for. 

Another kind of reminder, especially useful for remembering to add the salt after an autolyse, is to measure the salt for the bread into a small bowl at the same time you measure the water and flour, and put the salt bowl on top of the covered autolysing dough. So, when your alarm goes off, you don't forget the salt. (BTW, everyone has forgotten to add the salt at least once, unless they haven't baked long enough.)

Hi Dave,

I love your loaves and while living in Paris we were big, big fans of Gosselin/Kaiser/Julien school of baguette; products which we find ourselves missing statesite. I am a long time cook with some training, but my experience with sourdough is limited to the last couple months of experimenting and reading, your very inspiring tutorials and deep explanations on S&F, gluten development, the effects of steam, etc. I have also gone through the first few chapters of Daniel DiMuzio's "bread baking."

I have been trying to successfully execute the SJSD batard for a little while now. I have baked maybe 10 high hydration loaves in my life and think I am making progress but find myself a little stumped. Hoping you or someone on this blog with experience would give some very welcome advice.

In my last (best) attempt, I followed your instructions excepting the following:

My autolyse was extended to 2.5 hours instead of 1 due to an unexpected interruption in the day. To compensate I shortened the cold retardation to 16 or 17 hours.

I don't use the lava rocks, as I have a gas oven. I use an upside down half-hotel pan with a hole drilled on the side through which I inject steam using this. I steam only for 10 minutes, then remove the hotel pan and go convection at 430 as instructed.

I bake on a baking steel instead of a baking stone. (it's what I have)

I have not left the loaves to cool in the oven for 7 minutes (as I am baking one at a time), yes this may be the cause of my crust problems.

I live in Berkeley, CA, so our ambient temp is around 72 degrees during the day right now.

My problems:

- crumb is alternatively very large holes or dense; it is very shiny.

- crumb has good chew but is definitely on the humid side, which I don't mind so much, but the density is not good.

- crust is shiny and softens on cooling sapping the loaf of any crisp exterior

I am attaching pictures below.


Could I be underproofing?

Thank you all for any help.

Hi, Mrs. Renard.

I'm glad you have found my tutorials helpful.

Your San Joaquin SD looks pretty good to me. You have some fine tuning questions, I think.  I have some suggestions and a question.

1. The crust is going to get chewy. This is due partly to the high hydration and is partly just a characteristic of sourdough breads. You won't get the kind of thin crackly crust like a traditional baguette. Now, you can get a crunchier crust. Just increase the baking temperature10-20dF and reduce the bake time by 1-2 minutes. I prefer a bolder bake, myself.

2. The shiny crust is from steaming early in the bake. If you want less shine, steam less.

3. The shiny crumb. That is actually to be desired. The shine is from gelatinized starch. It's a sign of a well-baked bread, to me.

4. I've left the hard one for last - The dense lower crumb and huge holes in the upper crumb. This is not a rare occurrence with this bread. I think getting a tighter gluten sheath when you shape the loaf helps. I think proofing those loaves smooth side down on baker's linen helps. My question is: How are you proofing the loaves now?

I hope this helps.

Happy baking!

Thank you for your kind comments. I am trying a batch now with less steam and a bit higher temp. Yes, I agree shiny moist crumb is good. I should have guessed getting the density issue solved would be the hard part and would require better shaping. I will focus on getting a tighter gluten sheath.

I have been lazy and been proofing in (aggressively) rice-floured oval banettons. I just bought a chouche and I will switch to it and see what happens. I have a feeling my shaping needs practice and more practice. I get a good gluten sheath, but maybe I need to push it to get it at tight as I can without tearing (maybe it's kind of like getting an anglaise as thick as possible without curdling the egg ? ..... a fine line?).


Thank you for the feedback, it is much appreciated.

I've seen loaves of my own with similar crumb structure and crust color when they fermented too long before going into yhe oven.  

Second David's emphasis on the importance of good shaping.

I did have a very long autolyse in the loaf I pictured.... the batch cooking had a normal one, I will see what happens.

Thank you

Today's bake was remarkably better.

I even got ears!

The flavor was a lot sweeter and much, much better.

Here is what I changed:

I upped the temperature as recommended (470 then 450).

I steamed a lot less. Only at the very beginning.

I worked on tightening the gluten sheath in shaping.

I proofed a full 45 minutes on the first loaf, 60 minutes on the second.

Lastly I deepened my scoring.

While all the above certainly helped, I think you are right PMcCool.... those failed loaves were overfermented (during that too long autolyse), the leavening beasties were tired out and didn't want to get to work during that final proof (which is why I thought it was underproofed). Tomorrow I switch to the couche....

I have only the 2 photos below for evidence (one batard walked out the door with a friend and half of the remaining was attacked by DH)

... opened the oven at the end and dried out the crust. I got a bit of the crackly noise during cooling and a crust that, while not shatteringly crisp, still had some crunch.

Thank you both for your help!

Much improved crust and crumb. In fact, that SJSD looks about perfect!

You even achieved the characteristic tendency to disappear. ;-) Congratulations!
