I really did intend to make one of the 100 recipes I have saved from assorted websites and blogs or one of the 1000 recipes from one of my bread books.....really...I did. Well this recipe is kind of adapted from Peter Reinhart's The Bread Bakers Apprentice. I started with the recipe for Italian Bread and changed the biga to using my sourdough starter or levain and used European style flour, rye, barley and whole wheat flour instead of bread flour. I also added some organic cracked wheat bran to make it interesting and used molasses instead of sugar. Oh...and I used buttermilk instead of water...but other than that it's like I copied the recipe from the book!
The bread is rising in 2 bannetons as I write this, so I will let you know how it comes out at the end of this post....or if it doesn't turn out very well you may never read this :).
15.5 ounces 65% Hydration Starter Refreshed
6 ounces European Style Flour from KAF (you can use bread flour in place of this)
3 ounces Medium Rye Flour
2 ounces Barley Flour
2 ounces Whole Wheat Flour
2 ounces Organic Cracked Wheat Bran
11 ounces Luke warm buttermilk, 90 - 95 degrees Fahrenheit
1 2/3 Teaspoons Sea Salt
1 Tablespoon Olive Oil
1 Tablespoon Molasses
Using your stand mixer or by hand, mix the buttermilk with the starter to break up the starter.
Add the flours, salt, olive oil, and molasses and mix on the lowest speed for 2 minutes. Let rest for 5 minutes
Mix for 4 minutes more on medium speed, adding more flour if necessary to produce a slightly sticky ball of dough.
Remove dough to your lightly floured work surface and need for 1 minute and form a ball.
Leave uncovered for 10 minutes.
After another 10 minutes do another stretch and fold and put into a lightly oiled bowl that has enough room so the dough can double overnight.
Leave the covered dough in your bowl at room temperature for 1.5 to 2 hours and then put it in your refrigerator overnight or up to 3 days.
When ready to bake the bread, take the bowl out of your refrigerator and let it rest at room temperature for 2 hours. After 2 hours shape the dough as desired being careful not to handle the dough too roughly so you don't de-gas it. Place it in your bowl, banneton or shape into baguettes.
Let it sit at room temperature for 2 hours covered with oiled plastic wrap or a wet cloth.
Pre-heat oven with baking stone (I use one on bottom and one on top shelf of my oven), to 500 degrees F.
Slash loaves as desired and place empty pan in bottom shelf of oven.
Pour 1 cup of very hot water into pan and place loaves into oven.
Lower oven to 450 Degrees and bake for 25 - 35 minutes until bread is golden brown and internal temperature reaches 200 degrees.
Let cool on cooling rack and enjoy!
I do have to say the crust came out excellent on this bake and the bread had a nice flavor with a slight sour and nutty overtone. The crumb could have been a bit more open but overall I would consider this one a success.
