9/1/10 - Poilane Style Miche My Way/Liquid to Stiff SD Starter Conversion

Hey All,

Just wanted to share with you a project that I am working on...  So on 8/30/10, I took delivery of 75lbs of flour from King Arthur which I ordered because they were having a free shipping on certain items.  This included their AP flour along with their WW and White WW.  What to do, what to do...  So, I baked my first full sourdough bread without adding any yeast not too long ago: http://www.thefreshloaf.com/node/19389/83010-sourdough-progress with great success as far as open crumb, and crackling crust...  The flavor was very good, but there was one person who thought it wasn't salty enough or something...  Anyways, back to this project...

The previous sourdough bread was based on a liquid levain (100% hydration) which is also the hydration of my storage starter...  So my bright idea was to convert my liquid starter to a partially whole grain stiff starter at around 55% hydration...

On 9/1/10 at around 10:20pm, I threw out about half of my liquid starter, kept a small portion of it and mixed it as follows:

200g AP (King Arthur)

100g WW (King Arthur

150g Water

100g liquid sourdough storage starter (100% hydration)

550g total stiff starter yield

10:20pm - Mix all, place in covered container, let rest on counter.

12:20am - Place in refrigerator

 

9/2/10 - Feed Stiff Levain Again (Starter Build #2)

200g AP

100g WW

150g Water

550g All of starter from the evening before.

1000g total stiff starter yield

9:00am - Mix all, knead into ball, place into covered container, place in refrigerator.

 

9/3/10 - Final Dough

600g AP

200g WW

200g White WW (KA)

700g Water

24g Kosher Salt

600g Stiff Levain

2324g Total dough yield

6:18pm - Take stiff levain out of refrigerator and let rest on counter.  Give the levain the float test.  Measure out all ingredients.

Stiff levain out of refrigerator.  Notice the bubbles.

With a wet spoon, cut out a piece of the stiff levain and place it in some water to see if it floats...  If it does, it's ready to use.  For more on the float test, please check out this link: http://www.farine-mc.com/2010/01/building-levain-la-gerard-steps-2-3-and.html  Note point A3.

Cut up levain into pieces, place in large mixing bowl along with the measured amount of water required for the recipe.

Premeasured flours.  Note that on the bottom is the AP flour, and on the top the WW flours.

Kosher salt

All the ingredients in the bowl.  Notice that on the bottom is the water and stiff levain.  Then the whole wheat flours, the AP flour, then last on top is the Kosher salt.  This sequence is very important, and will prevent the formation of lumps or dry clumps, and dry bits stuck to the side of the bowl.

Beginning the mixing at 6:57pm.  I am using a large plastic/rubber spatula.  This is the initial mixing which takes about 30 seconds.  You can pretty much keep the spatula stationary and move the bowl at this stage.  It is just to mix the wet ingredients with the dry ingredients.

This is probably about 1 minute of mixing.

A little more mixing.

Done mixing with rubber spatula... Now time to get wet and dirty with hands and water...

This is the dough after the following: make sure you have a bowl of water next to you...  Wet your hands and squish the dough in order to work out any lumps...  Then slap fold and roll two times.  This technique that I use is a hybrid of what Richard Bertinet does with in his sweet dough video, except I prefer to do it all in my mixing bowl to prevent getting my kitchen counter sticky and messy: http://www.gourmet.com/magazine/video/2008/03/bertinet_sweetdough

1.  Take the ball of dough by one end, let it stretch down using gravity.

2.  slap the bottom part of the dough into the bottom of the bowl.

3.  Fold the top part that you are holding into the center, and roll it into a ball in one forward motion.

4.  Rotate bowl 90 degrees and repeat.

Place entire bowl into large plastic bag, autolyse (rest) for 30 minutes...  Have a cup of coffee, tea, or beer...  I'm having beer...  Just as a note, these series of steps lasted from 6:57pm to 7:02pm, which is about 5 minutes out of your life...

Dough after 30 minute autolyse.

7:40pm - Dough after 2 slap, fold, and rolls...  Sorry for the blurry pictures.  Notice how much smoother the dough is...

Dough after about 10-15 slap, fold, and rolls...  Notice the dough tear at the bottom.  At this point when this happens, stop handling the dough, place it in plastic bag and wait for about 20-30 minutes.

8:00pm - This is the dough after the 20 minute rest, and 6 additional slap, fold, and rolls...  Place bowl in plastic bag, let rest for another 20 minutes.

8:20pm - This is the dough after the 20 minute rest.  Notice how it has spread out...

This is the dough after 2 slap, fold, and rolls...

Transfer to plastic tub lightly oiled with extra virgin olive oil.  I'm sure any sort of neutral cooking oil would work.  My tub is a 4L tub, which is the smallest tub you would probaby want to use for the amount of dough this recipe makes...

Top view.  Sorry for blurry...

Added plastic wrap before putting on top.  My containers don't seal all that great.  Plus, it's insurance if the dough pops the top in the fridge...

Place in to fridge...  40F to 45F...

9:25pm - Turn dough, return to fridge...

9/3/10 - The moment of truth...

I was at work for longer than I had intended today...  Argh!

5:00pm - Do I have magical dough, or a dough explosion?

Dough Explosion!!!

Release my cornichons!!!

Dough texture shot...  Looks well fermented...  Fingers crossed...

5:00pm - After I cut off the dried bit from the exploded part, I divided the dough and shaped them into boules weighing approx 1100g.  The dough shaped nicely without tearing...  More fingers crossed...  Now for proofing for about 2 hours...

Bannettons in plastic...

5:50pm - It's pretty warm right now... 85F in the kitchen...  Proofing going well.  Turned on oven with 2 stones, steam pan.  Preheat to 550F with convection for 45 minutes to 1 hr...

7:10pm - Take the baskets out of the plastic, give it the poke test, take the thermometer out of the oven, prepare one cup of water, locate oven mitt, lame, peel, cup of flour, turn convection off...

Slash as desired...

Peel directly on to baking stone, put oven mitt on, carefully pour one cup of water in steam pan, snap picture, close oven door, turn down to 450F without convection.  Bake 50 minutes, rotating half way...

This is one of them halfway through the bake.  I rotated them, and shifted them between the upper and lower stones...  25 more minutes of baking, and then a weight and temp check...  I'm shooting for 935g or less after bake weight which puts it at a 15% weight loss, which is good...

8:00pm - Weight and temp check...  Weight around 980g, and internal temp is around 200F...  I'm looking for 210F...  Bake for another 10 minutes...

Will post crumbshots tomorrow...  Enjoy!
