9/23/10 - Tourte Auvergnate with Rye Sour

Hey all,

Just wanted to share with you this bake from 9/23/10.  It is a Tourte Auvergnate inspired by the recipe in Le pain, l'envers du décor by Frédéric Lalos.  His version is basically 80% rye, and the rest in white flour, which is made into a stiff levain.  I decided to make mine with 75% rye flour, and 25% AP flour.  I made the AP flour into a stiff levain, and then with some of the rye flour, I made a rye sour.  Here's the formula, process, and pictures.  Enjoy!

Process:

9/22/10

6:30pm - Mix rye sour and stiff levain, cover and let rest on counter.

7:00pm - Put stiff levain into refrigerator.

9/23/10

9:00pm - Weigh out all ingredients, and place into large mixing bowl in the following order, water, levain, rye sour, rye flour, salt.

9:15pm - Mix for 5 minutes starting with a rubber spatula and switching to wet hands as the dough gets harder to stir.

Switch to wet hands and knead dough.

9:20pm - After mixing and kneading, cover and let bulk ferment for 1:30...

10:50pm - Dough after bulk ferment.  Notice the poke in the top part.

10:55pm - Divide and shape.  I made 3 relatively equal size boules.

Place in floured bannetons seam side down.

Cover and let proof for 1 hour.  Place 2 baking stone/stones in oven with steam pan filled with lava rocks and water.  Preheat to 550F with convection.

11:55pm - Turn off convection. Turn boules on to floured peel/flipping board and place in oven directly on stone.  When last one is in, pour 1 more cup of water into steam pan, close door and turn oven down to 500F no convection.  Bake for 10 minutes at 500F.

9/23/10

12:05am - Take out steam pan, turn oven down to 420F.  Bake for 20 minutes.

12:25am - Rotate loaves around, or between stones.  I am baking on 2 stones, starting them off on the bottom, transfering them to the top.  Bake for another 20 minutes.

12:45am - Take one loaf out to check weight and internal temp.  Should be at least 15% lighter than prebaked weight, and internal temp should be about 210F.  Turn oven off, and leave loaves in for another 10 minutes.

12:55pm - Take loaves out and let cool at least 24hrs before cutting and eating to let the crumb stabilize and dry out a little.

8:00am - I was a little impatient so I cut into one so I could see the crumb...  Slightly gummy as I had expected, but after a little toasting and butter, it was all good...  Enjoy!
