The only changes I made was to build the levain using Durum flour in a 2 step build. I also used garlic infused olive oil instead of plain olive oil. I also used a new proofing basket I just purchased which fit the amount of dough produced perfectly.
The results were excellent. I like the flavor and creamy texture the increased durum starter imparted on the final bread.
Here are the Zip files for the above BreadStorm files.
Tangzhong is the technique of heating a portion of the flour and liquid in your recipe to approximately 65C to make a paste (roux). At this temperature the flour undergoes a change and gelatinizes. By adding this roux to your final dough it will help create a soft, fluffy, moist open crumb. It is also supposed to help prevent the bread from going stale.
It is not very difficult to do a Tangzhong. Use a 5 to 1 liquid to solid ratio (so 250g liquid to 50g flour) and mix it together in a pan. Heat the pan while stirring constantly. Initially it will remain a liquid, but as you approach 65C it will undergo a change and thicken to an almost pudding like consistency. Take it off the heat and let it cool before using it in your recipe. Some people will refrigerate it for a while but you can use it right away as soon as it cools.
Levain Directions Build 1 (Using AP Starter at 66% Hydration for Seed)
Mix all the levain ingredients together for about 1 minute and cover with plastic wrap. Let it sit at room temperature for around 7-8 hours or until the starter has doubled. I used my Proofer set at 81 degrees and it took about 4 hours.
Levain Directions Build 2
Add the ingredients to the Build 1 levain and mix thoroughly and cover. Let it sit at room temperature until the starter has doubled.
Main Dough Directions
Prepare the Tangzhong per directions above and allow to cool to room temperature.
Mix the flours, Tangzhong and water together in your mixer or by hand until it just starts to come together, maybe about 1 minute. Let it rest in your work bowl covered for 20-30 minutes. Next add the salt, oil and starter (cut into about 7-8 pieces), and mix on low for a minute. Mix for a total of 6 minutes in your mixer starting on low-speed and switching to speed #2 for the last 2 minutes. Remove the dough from your bowl and place it in a lightly oiled bowl or work surface and do several stretch and folds. Let it rest covered for 10-15 minutes and then do another stretch and fold. Let it rest another 10-15 minutes and do one additional stretch and fold. After a total of 2 hours place your covered bowl in the refrigerator and let it rest for 12 to 24 hours. (If you have a proofer you can set it to 78 degrees and only leave the dough out for 1 hour to 1.5 hours before placing in the refrigerator).
When you are ready to bake remove the bowl from the refrigerator and let it set out at room temperature still covered for 1.5 to 2 hours. Remove the dough and shape as desire and cover with a moist lint free towel or sprayed plastic wrap.
The dough will take 1.5 to 2 hours depending on your room temperature. Let the dough dictate when it is read to bake not the clock. Note: I used my proofer set to 80 degrees and it took a little over an hour to be ready.
Around 45 minutes before ready to bake, pre-heat your oven to 550 degrees F. and prepare it for steam. I have a heavy-duty baking pan on the bottom rack of my oven with 1 baking stone on above the pan and one on the top shelf. I pour 1 cup of boiling water in the pan right after I place the dough in the oven.
After 1 minute lower the temperature to 450 degrees. Bake for 35 minutes until the crust is nice and brown.
Let them cool on a bakers rack before for at least 2 hours before eating.
