Baking sourdough bread, Joost style

I've been baking bread for quite a few years and have also been experimenting with sourdough for a similar time period.
As of lately I've come to a more standardized approach, and I thought it interesting to share it.

Starter


I keep a bit more then 100g of started in a closed glass bowl in the refrigerator. This is a started that I made myself from just a collection of flours, making it what is called a "wild" starter. Making starters is a whole topic in itself, so I won't go into it more in detail here. I might write a blog post about it in the future.

Mixer


I use an old-school Kenwood mixer for kneading Of course you can also do it by hand, but it's sticky business ;)

First remove the bowl from the mixer and put the sourdough starter in it.


Put the bowl on a scale and reset the scale to 0.


Dough

Time to add flour. We're going to add 600g in total. For this bread I used 50g buckwheat, 100g rye and 450g organic whole wheat flour.


Flour added to bowl.


Next lets add a teaspoon of salt. You can go completely salt-less if you like but I prefer just a tad of salt to enhance the taste.


Next add about 20g of vegetable oil. I used olive oil here.


Time to add water. I use a bit more then 400g (== 400ml) water. The amount of water needed is somewhat dependent on the flours you use, but it's typically roughly 2/3 the weight of the flour. 

Water of about 28 degrees Celsius (82 Fahrenheit) is perfect but cold water also works just fine. For kicks I rinse the glass bowl with the water to already somewhat clean it and get some more starter in the water while at it.



As you can see I got a little more water then planned but that ok (600g flour + 470g water = 1.070 kg). It's actually a good idea to have a bit more when using buckwheat like I am here.

Mix


Mixing...


Done.

Rise

Now we want to store the dough for about half a day for a rise period. Cover it up with a cloth while rising and place it at a warm spot in the house. I put it near the heating system in our house.


After the rise period it is grown in volume.


Cool

Now it is time for a cool period. Store the sourdough (still covered with cloth) in the refrigerator for at least 12 hours. I usually just leave it overnight.

The next morning it'll be further grown in volume.


Mix again



Mix the dough a second time, mostly to remove all the air from it.

Store starter


Store a bit more then 100g of the dough in your glass bowl back in the refrigerator. This will be the starter for your next bread. If you want to store it for longer then 2 weeks, put it in a plastic bag in the freezer.

In mold



Put the dough in a mold. I use a silicone cake mold. It is a sturdy one with extra ribs on the side which I recommend. A metal mold also works but you may want to oil/grease it. Do NOT use Teflon coated metal molds. The sourdough is quite strong and it can actually peel of the Teflon coating, which is toxic!

Room temperature


This step can be skipped but gives a nicer risen bread. Cover the form with your cloth and let it stay like that for a few hours to reach room temperature.

After this period the dough has slightly risen again.



Bake

Put in a cold oven and set the oven to 60 degrees Celsius (140 Fahrenheit). I use top and bottom heating and no convection.



Let it at this temperature for 15 minutes.



Then switch to 100 degrees Celsius (212 Fahrenheit). Stay at that for another 15 minutes and then switch to 175 degrees Celsius (347 Fahrenheit).
Keep that final temperature for 30 more minutes, or a little more if you like your bread crusty.

Bread

Take the bread out of the oven, and let it cool down on a riser to allow airflow all around it.



Eat



Enjoy.

Cleaning

A great tip for cleaning all the utensils covered with dough: do not use warm water, use cold water! Warm water makes dough more sticky. Cold water not so much.
