Chia Seeds Rye Sourdough - Another Weekend with Rye


Another weekend baking with light rye bread and continue keeping with 20% rye flour.

Last week's light rye bread with overnight retardation (chilling the shaped doughs in the fridge overnight to slow down fermentation) yielded too acidic loaves to my liking. So, this week I used the white starter instead of rye starter in the recipe, which I was hoping to reduce the acidity (sour taste).

I also added chia seeds into the dough as I planned to give some of the bread to S'mom when she came over. We were introduced (or heavily convinced) to the chia seed goodness by her. Apparently, this seed is a super food. It is rich in omega-3 fatty acid, protein and fibre. She gave us a big bag and tried to convert us into chia seed devotee.

I soaked the seeds with 1.5 part of water (1 g seed:1.5 g water). The seeds appeared to soak up all the water and became thick jelly paste. It was impossible to drain any water out of the seeds.  The dough became really wet after the seeds were incorporated (I mixed the seeds in after the gluten has developed). As a result, I had to do the stretch and fold in the bowl (to strengthen the gluten structure further). I also had a slight (very slight) trouble shaping this rather wet dough. Shaping the wet dough is always a bit of a challenge. It was a challenge to create enough surface tension without tearing the dough surface. I tried not to add too much flour and brushed the excess flour whenever possible. 


Chia seed turned into gel-paste after they were soaked in water

I baked one loaf in a pan and the other as a freestanding loaf. The level of oven spring was clearly visible at the one baked in loaf pan. The crust colour was virtually different between two sections, the bottom and the top bit (pale colour on the section of original dough volume and dark colour on the oven spring section). It was interesting to see how much volume the dough has gained after the bake.


The bread gained significant volume as evidenced by the different crust colors

Before and after

I also tried a new oven steaming method recommended by Chad Robertson in Tartine Bread book (baguette recipe section). Mr Chad suggested placing soaking wet tea towel in a baking pan at the bottom of the oven when it is pre-heated. I also added about half-cup of water into the towel tray twice during the first 10 minutes of baking. The towel tray was removed after first 15 minutes. I also combined this steaming towel with my usual boiling water with pre-heated cast iron pan. It created so much steam that the smoke alarm went off! The alarm was off a few times when I opened the oven to pour more water into the towel. I think I would have laughed at myself if I happened to videotaping my actions. I was jumping onto the kitchen bench with my kitchen towel, waving away the steam from the smoke alarm. The alarm stopped. I stopped waving the towel. The alarm went off again. Waving towel again. Stopped, and sitting on the bench, swinging my legs and wait to see if the alarm would be off again. You know how smoke alarm can be really loud and so alarming.

I love this new steaming method. It provided better loaf volume and shinier crust. It also removed the need of constant spraying the oven for the first 10 minutes (it also means no open-and-close the oven every minute for spraying and the oven heat was more contained).


Nice and shinier crust with the new steaming technique
 The bread was nice and moist which gave a great chewy crumbs. It was mouthful and a pleasant to eat. I believe that the gel-texture of chia was turned into liquid and got absorbed in the crumb and contribute to the softer bread texture. Chia seeds also gave a slight crunch and texture to the bread. The bread got just-right sour taste, not too acidic. I think by using white starter instead of rye starter gave less sour flavour. Personally, I think using rye starter at 20% rye percentage bread with overnight retardation would yield too sour a bread for me. If I am to continue retarding my dough with 20% rye flour and over, I would use the white starter instead of rye starter. However, this is my personal preferences. I like this flavour profile (with white starter) better. It has the sweet and nuttiness from wheat and slight acidity and earthiness from rye.

Chia seeds seemed to get lost in the crumb


A quick notes from this week's bake:

·         Sourdough bread with 20% rye flour using white starter instead of rye starter
·         New steaming method, a tray of wet towel placed in the oven while it was pre-heating. It provided much more streams, great oven spring and shinier crust.
·         Chia seeds turned into gel-paste after being soaked and contributed to very moist crumbs. The bread was lovely with a chewy tender crumbs.
·         I bake two loaves, with one in the pan and the other free-standing, at the same time with the same temperature. The pan-loaf weighted 1.3 kg (before baking).  As you might have guessed, the pan-loaf got softer crust. Given that it is a lean bread, without fat and sugar, it got rather pale crust. I generally like crusty bread. However, it is such a nice change to have soft bread with soft crust. It’s nice to give my jaw a break sometimes.
·         I also baked them slightly longer due to its high liquid percentage.

Here is the recipe…

Chia Seed Rye Sourdough

Bread flour
1032 g
80%
Rye flour
252 g
20%
Water
938 g
73 %
Salt
25 g

Soaker

Chia seeds 65 g
Water 98 g, room temperature
Total 163 g

Final dough
White starter (100% hydration) 450 g, active starter
Bread flour 807 g
Rye flour 252 g
Water 615 g
Salt 3 teaspoons, 25 g
Soaker all of the above

METHOD

Prepare soaker: Mix chia seeds with water about 12 – 18 hours before the baking. Let it sit in a covered container at room temperature.


Mixing: Add all the ingredients to the mixing bowl, except salt and soaked chia seeds.  Mix until the ingredients are incorporated. Leave it to autolyze in a bowl covered with plastic bag or wrap for 15 minutes. 

Sprinkle salt over the dough surface and mix on the first speed for 3 minutes and continue mixing on second speed for further 3 – 4 minutes, until a strong gluten development is achieved. If mixing by hand, it would take approximately 15 – 20 minutes to have a well gluten development. Desired dough temperature is 80F/26C

Mix chia seed soaker through until they are well-incorporated into the dough.

Bulk fermentation: - Leave the dough in a lightly oiled container and cover the bowl with plastic bag or wrap for 2 – 2.5  hours. Do the stretch and fold twice at 50 minute and 100 minutes (every 50 minutes intervals).

Divide the doughs into two equal portions (I made it into 1.3 kg and 1 kg portions. 1.3 kg was for the loaf pan). Pre-shape the doughs into rounds and let them rest for 15 minutes under a tea towel. Shape the doughs into oblong (batard) or round (boule) and place into proofing baskets/bowls. Slip the proofing basket into a large plastic bag and retard the dough in the fridge overnight, between 8 –12 hours. 


Baking: take the doughs of the fridge. Let them sit at room temperature to continue its proofing. This will take between 1 –2 hours depending on the room temperature. In the meantime, preheat the oven to its highest temperature.

Bake at 240
°C (460°F) for 15 minutes with steam, then lower the temperature to 225°C (440°C) and bake for another 25 – 30 minutes.

Leave the loaves to cool down in the oven with the door ajar. This is to help the bread drying out thoroughly with its internal moisture.

  1. Hello Sue,

    I like the shining surface breads; maybe I will buy chia seeds in the future, I have others seeds that need to use up ASAP before they go bad. I’m quite scare to use the wet towel method you mentioned above since I do worry the towels get too dry during baking, I may tried your method when I have spare time in future. Thanks.

  2. Hi Kimmy,

    I think any other seeds would work fine but you will have to adjust the water in the soaker.

    I was scared of towel got on fired in the oven as well. It all went fine without any problem. Though, I put about 1/2 cup water onto the towel once during the preheating. And then put more water twice more during the first ten minutes of the baking.

    When I removed the towel from the oven after 15 minutes of baking. They were still moist, very moist with lots of steam.

  3. Hello Sue,

    I have some thai basil seeds leftover in my freezer, do you think thai basil seeds maybe a good substitute for your recipe? Your new post make me soooo hungry right just get back from work.

  4. It's funny Kimmy, you mentioned thai basil seeds. I was thinking about the Thai Basil Seeds that some of its attributes are quite similar to chia. How they absorb water, swell and turn into gel. I have never tried (or ever came across thai basil seeds in bread in Thailand) using them. But I got a feeling that it should work. Maybe half the recipe for experiment, and see how you go. It sounds like fun when you're experimenting something new. I'd love to know how you go with it:)

  5. I love chia seeds and use it to make 'raw' puddings or simply mix it with yogurt but I would love to use it in bread. I love your blog and will subscribe in a second.

    I'll let you know how the bread turns out, looking forward to it.

  6. Thanks, Megi.

    We do put chia seeds in our bircher muesli too. It adds nice texture to the muesli. Chia and yogurt sounds interesting. Sounds like a good quick low GI snack too.

  7. Oh I think your loaves are gorgeous, love the spring and crackly crusts! I need to resurrect my starter but I can get some chia gel going; I don't go through it incredibly quickly but I do so love rye bread, I may start now.

  8. Thank you. Hobby baker:)

    I was surprised how resilient SD starter can be. I went away for over a month, came back, refreshed the starter a few times and it was back to life...
