Sourdough baguette experiment -- Success!

Usually when I get it in my head to cobble together a formula based on two or three things I've seen mentioned on this forum, two more in my head, and a bit of whimsy, the results are not pretty.  Especially when it comes to baguettes.  The last two or three times I've tried to make baguettes, they've come out flat, with closed crumb and, with the sourdough versions, crust that provides a thorough jaw workout.

But not this time, oh no!  This time I tasted victory.  Victory, and some very yummy bread.

Here's what I was trying for:

  • 100% Sourdough baguettes
  • All white flour
  • Two preferments (saw this mentioned a couple places and it sounded good).
  • Roughly 65% final hydration (also based on some other posts at thefreshloaf)

To this I arbitrarily decided that 50% flour weight would be prefermented, of which about half and half from a 50% hydration pate fermente and a 100% hydration wet starter.  Because, y'know, why not?  I decided on 700g total flour and worked out the math to get:

  • 340g wet starter (170g flour, 170g water)
  • 273g pate (180g flour, 90g water, 3g salt)
  • 350g final flour
  • 200g final water

Got to set up a bakers math calculator for myself.  Anyway, the formula ended up being thus:

Liquid Levain

  • 32g active starter (I'd converted part of my firm starter to 100% hydration the day before, but I doubt it matters much)
  • 150g Stone-Buhr bread flour
  • 150g water, room temperature

Sourdough Pate Fermente

  • 45g active starter (50% firm starter, in this case)
  • 150g Stone-buhr bread flour
  • 75g water 
  • 3g salt

Mixed starters at about 9:30pm the day before baking and let them sit overnight.  My firm starter had been in the fridge since that morning, so I used warm water for the pate. Began the next stage at 7:30 the next morning.

Final Dough

  • 350g Stone-buhr bread flour
  • 200g water, room temperature 
  • 11g salt
  • Liquid Levain (all)
  • Sourdough Pate (all)

Mixed Flour, water, and liquid levain until a shaggy mess, then covered and left to autolyze for 45 minutes.  Held off on adding the pate partly because it seemed like The Proper Thing To Do(TM), leaving out the salt and all that...but mostly because the pate looked pretty sluggish and needed at least another 45 minutes to ripen.

Added pate and salt and kneeded for a couple minutes.  The stiff pate really didn't want to incorporate, so I gave it a 5 minute rest then kneaded a little more until the lumps were more or less dispersed.  Then it was into a bowl to rise.

I gave the dough 30 folds in the bowl with a rubber spatula after 30 minutes of fermentation, then again after 2 hours.  Total time for the first rise was 5 hours (I meant for it to be 4, but got confused, and anyway it wasn't rising hugely).

Preshaped the dough into 4 ~10oz pieces (yeah, yeah, switched measuring systems midway), and let rest for 10 minutes.  Then final shaping, and rising on my well-floured couche-tablecloth for 2 hours.

Baked at about 475 (my oven's temperature sensor is wacky) with steam for 22 minutes, opening the oven a crack after 10.  Then left the oven cracked and turned off for another 5 minutes before removing the baguettes from the oven.

The results:

Another Angle

Crumb Shot

 I was incredibly pleased with the results here.  The scoring is easily the best I've ever done, though there's clearly room for improvement.  The mere fact that the things didn't turn out flat was a huge improvement of my last attempt at a sourdough baguette.  The crumb turned out well.  The flavor was wonderfully complex, moderately sour, with a thin, crisp crust that was just slightly chewy (hey it's sourdough, after all).

"Adjusting" sourdough starter

Last week's result

Yesterday's result

Using Daniel DiMuzio's guidance, both from his latest book "bread baking, An Artisan's Perspective", and following his posting here on TFL,  I've been working with two different sourdough starters,from different sources. One contributes flavor much to our tastes for sourness, but disappointing in proofing times, and lacking in oven spring, and a second starter that has been phenomenal in yeast activity, i.e., proofing and oven spring, but dissapointing in our preferred sourness. Both starters are maintained in the refrigerator at 100% hydration.

Last week, using Daniel DiMuzio's pain au levain formula with firm levain (480g ripe firm levain, 700g total flour, 68% hydration) I built my firm levain at room temperature (76°F) from the first sourdough starter with three builds, spaced approximately 8 hours apart, gradually increasing the mass three times each build, and, simutaneously, reducing its hydration by one-third each build. DiMuzio's formula calls for a pre-ferment 60% hydration, I chose to match the dough target hydration, 68%, because I wanted to keep the build as wet as possible during its ripening hopefully favoring yeast development. I visually checked its progress and fed it its scheduled builds based on observable peaks; nevertheless, the build interval was nearly eight hours each time.

Expect for using all white flour, I followed Dan DiMuzio's formula exactly. I mixed the dough in my stand mixer for five minutes, allowed it to rest 30 minutes, and bulk fremented it with three stretch and folds spaced at 45 minute intervals. Doubling took approximately, three hours after the final stretch and fold. I shaped two boules (one 1-1/2 lb, one 2 lb); proofing took 2 and 1/2 hour. I baked the loave at 480°F, covered, with steam, for the first ten minutes, reduced the oven temperature to 450°F, uncovered the loaves and baked for another fifteen minutes until internal temperature was 206°-208°F.

The results were very gratifying. The proof times were nominal, compared to most sourdough recipes I've read or tried, and the oven spring was adequate, attested by first photo. I didn't get a photo of the crumb; it was close but light and airy, not dense; and the flavor was delightful to our palletes.

For three days immediately prior to yesterday I've been caring for a firm levain, built from the second starter (great yeast activity, disappointing sourness). Starting with 50g of seed starter, I added sufficient flour to immediately reduce its hydration to 65%, subsequently I fed it, approximately, every eight hours, maintaining its 65% hydration, ending early yeasterday morning with 480g of ripe firm levain. My goal, of course, had been to favor bacterial growth, as Dan suggests, over the extended build period.

I made the dough, shaped and baked the loaves as identically as possible to the first starter test. Proof times were, as expected shorter: 2 hours, and 1 and 1/2 hours respectively.

The results were equally gratifying, The levain retained its previous yeast activity, and the level of sourness we hoped for was achieved. The crumb is nearly identical (perhaps a little more open) compared to the first starter's loaves. The first two loaves are history, so I couldn't do a side by side comparison.

For sourdough, I'm satisfied, for now, with the three step build (increase/decrease by thirds from seed mass and hydration) I'm using, so I don't think I'll do anything with the first starter. On the other hand, I'm considering ways to improve the second starter's bacterial contribution to flavor, but ultimately regain its maintenance hydration, and the ability to build a ripe levain in one day. I suppose the most obvious thing is repeat the three day firm levain build, and then use my twenty-four hour three-build modification back to maintenance hydration. Waiting is...

Motherdough,


I decided to post pix of my motherdough which is where this all started. It has a very short history at this time but hopefully it will last a few years and I can pass it down and around. Flour and water.
