Coffee Potato Sourdough
Warning...if you don't like the flavor of coffee you will not like this bread. I have used coffee in my breads before and usually it is very subtle since I use a higher percentage of whole grain flour and add-ins but since most of the flour in this bake was on the white side the coffee flavor was very strong.
This bread did come out very nicely and the addition of the potatoes in combination with the Durum flour, sprouted whole wheat and dark rye really produced a nice open and moist crumb. As usual I couldn't leave well enough alone and had to add some garlic olive oil, dried shallots, cheese powder and aged balsamic vinegar which really added to the complex flavor profile of this bread.
If you don't like coffee you can replace it with water and you will be very happy with the way this bread turns out.
I was doing some research on the hydration levels of different ingredients and discovered that boiled potatoes are 81% water which really helps create a moist dough but not enough to make this dough unmanageable.
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 usually do this the night before.
Either use in the main dough immediately or refrigerate for up to 1 day before using.
Main Dough Procedure
Mix the flours, and 350 grams of the coffee 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, starter (cut into about 7-8 pieces), and the rest of the ingredients and mix on low for a minute. Next add the rest of the coffee unless the dough is way too wet. Mix on low-speed for another 4 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.
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 desired. I made 2 loaves using my bannetons. Place your dough into your proofing basket(s) and cover with a moist tea towel or plastic wrap sprayed with cooking spray.
The dough will take 1.5 to 2 hours depending on your room temperature. Let the dough dictate when it is ready to bake not the clock.
Around 45 minutes before you are ready to bake, pre-heat your oven to 500 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 a shelf above the pan and one on the top shelf.
Right before you are ready to put them in the oven, score as desired and then add 1 cup of boiling water to your steam pan or follow your own steam procedure.
After 1 minute lower the temperature to 450 degrees. Bake for 35-50 minutes until the crust is nice and brown and the internal temperature of the bread is 205 degrees.
Take the bread out of the oven when done and let it cool on a bakers rack before for at least 2 hours before eating.
