8/30/10 - 2 Stage Liquid Levain Sourdough Boules

8/30/10 - 2 Stage Liquid Levain Sourdough Boules

So this is an interesting bread for me.  It's the first full sourdough bread of my official baking season.  It's still quite hot here in NYC, around 90F, so my kitchen is in the 80's...  I wasn't sure what to bake, but my sourdough starter needed feeding, so I figured what the heck.  So the starter was fed at 7:00pm, and it doubled in 2 hours.  I took out 200g of the refreshed starter, and fed it again as below, and it doubled in a little over 2 hours to my surprise...  So I made my dough as below, and fridged it, not expecting much...  In the morning when I woke up, it had doubled in the plastic containger (4L).  I gave it a turn, put it back into the fridge and went to work...  When I came home at 6:30pm it had hit the top of the container, and by 7pm, it had popped the top...  Now time to prepare to bake before a dough explosion happens...  Usually when I do these levain only breads, I'm sitting around waiting for it to do it's thing...  This time, I had to bake when it was ready...  Now!  Enjoy the pics...

12:15am - Mix all into shaggy dough, cover let autolyse for 30 minutes.  Prepare oiled plastic tub.

12:45am - Turn dough using French fold method with wet hands and dough scraper in bowl  until dough smoothes out and tightens up.  Stop when gluten starts to tear (turn not more than 8-10 times).  Transfer to oiled tub, place in refrigerator at 40-45F.

1:25am - Turn dough, return to fridge.  Go to bed.

8:35am - Turn dough, return to fridge.  Go to work.

7:20pm - Take dough out of fridge, divide into 4 equal pieces, preshape... (576g approx)

7:30pm - Final shape into boule, place in banneton for proofing, cover with plastic.

8:30pm - Place baking stones in oven on 2 levels along with steam pan, preheat 550F with convection...

9:30pm - Turn convection off.  Turn boules out onto peel, slash as desired, place in oven directly on stone.  When all boules are in, pour 1 cup of water into the steam pan, close door, turn oven down to 450F.  Bake 45 minutes, rotating loaves between stones and positions halfway through bake.  Boules are done when internal temp reaches 205F or more.  Let cool completely before cutting (overnight).

Out of the oven, the boules weighed about 470g, which is about an 18% water loss, which is good.

I'll post a crumbshot tomorrow...
