The texture is especially soft and moist on the first day and it lasts very well for 2 - 3 days.  I could not taste any sourness of this bread.

I was so happy with how my Sourdough Shokupan using the sweet stiff starter turned out.  So, I am  on a journey of rebaking my old recipes using a sweet stiff starter method instead.   With this sweet stiff starter, I found that the bread proofs noticeably faster.  I use a high percentage of stiff starter that help to cut down proofing times and make the bread rise faster.

How To Make Orange Sweet Potato Soft Sourdough Bread


Yields:  1 loaf  

INGREDIENTS:

Sweet Stiff Starter:
56g sourdough starter (100% Hydration), use at its peak 
172g bread flour (I used Japan High Gluten Flour)
72g water
28g sugar (I used organic brown sugar)

Main Dough:
130g bread flour (I used Japan High Gluten Flour)
115g mashed orange sweet potato (about 200g potato - peeled, sliced, steamed and mashed)
All the sweet stiff starter
10g brown sugar 
1 tsp salt
50g milk (Reserved 10g and add in all if needed.  I used total 50g.  The amount of liquid also depend on the hydration of mashed sweet potatoes and also the flour type)
40g whisked egg (from 1 large egg and keep the balance for egg wash)
30g butter 

Egg Wash:
Balance of the egg wash + 1/2 tsp water

Utensil:   
450g loaf pan (21.3 X 12.2 X 11.5 cm  /  8.4" X 4.8" X 4.5")

METHOD:
  1. Sweet Stiff Starter 
    1. In a bowl of stand mixer, dilute starter with water, stir in sugar and add in bread flour.  Mix with paddle attachment until well mixed and all come together.   It can be done by hand mixing too.
    2. Cover and let it ferment until tripled. I prepared a night before and leave it in aircond room (approximately 24 - 25C room temperature) overnight until tripled.  It took about 8 - 9 hours depending on your starter.  It should take around 4 - 6 hours to get triple at room temperature at 28C - 30C. 
  2. Main Dough:
    1. Put all ingredients (except butter) into a bowl of stand mixer.  I usually slightly torn the stiff starter dough first.
    2. Slightly combine the mixture by hand with the paddle attachment before turning on the machine so that the flour will not splash out.  Using the paddle attachment, mix for 2 minutes or until all incorporated.  This step is critical to prevent  an uneven mixed dough as the stiff starter is rather hard and a dough hook may not be able to mix it well enough.
    3. Change to hook attachment and knead for another 3 minutes or until the dough comes together. Add in butter and continue knead for 10 - 12 minutes or until reach window pane stage.  During the whole kneading process, I stopped few times to scrape down the dough from the hook to be sure it is evenly kneaded and also to prevent the motor from overheating.
  3. First Proofing/Resting The Dough:  
    1. In the same bowl, let the dough rest for 45 - 60 minutes. 
    2. This dough I rested for 45 minutes at 29C - 30C room temperature and the dough rose slightly. 
  4. To shape:
    1. Punch down the dough to release the air. Transfer the dough to a clean floured surface.  You can divide the dough into 2 or 3 equal portions if you like.
    2. Flatten with rolling pin into a big dish.  
    3. Fold right to centre and fold left to meet in the centre. Roll out with rolling pin into long rectangle shape. Roll up the dough like Swiss Roll until a small log is formed.
    4. Place all dough in a loaf pan.  
  5. Final Proofing:
    1. Let it proof at warm place until the dough reaches the height of the pan.  This one took approximately 2 1/2 hours at room temperature of 28C - 29C.  The duration of proofing depends on your ambient temperature and starter.
  6. To bake:
    1. Preheat the oven at 190C (top and bottom heat) or 170 (fan-forced mode) 10 - 15 minutes before baking.
    2. Brush with egg wash.
    3. Bake at preheated oven for around 30 minutes, or until golden brown.
    4. Remove bread from oven and let it cool completely on rack before slicing.
Preparing Sweet Stiff Starer


GENERAL NOTES:

SOURDOUGH STARTER


A healthy starter is very crucial as advised by Baking with Gina.   It is advisable to feed your starter regularly if you want your bread to rise nicely and to use the starter (levain) at its peak.  A starter that is fed regularly will be more active in general.  If the mother starter is not strong, the bread dough will not rise a lot even though the starter is used at its peak.  


GLUTEN DEVELOPMENT & WINDOWPANE TEST

Gluten forms when flour comes in contact with water.  Hydration of the flour causes the sticky and stretchy protein to form, giving structure to the bread.  This makes your bread trap air and rise. 

Gluten in dough can be developed by autolyse, resting, kneading or folding.

The windowpane test is used to determine whether the dough has been sufficiently kneaded.  By gently pulling the dough (or you may pinch off some dough) and trying to stretch it into a thin membrane.  If you are able to stretch the dough paper thin and translucent  without tearing, then the gluten is fully developed.  However, if you can stretch it without tearing but the membrane is not transparent, then the gluten is not yet fully developed.  

However, from my experience not all the recipe can achieve a thin and translucent window pane stage easily.   For example low hydration and low fat dough.  For such recipes, a reasonable window pane is good enough and it can be left to rest. Gluten will continue to develop while resting.  Exercising restraint to not over-knead the dough prevents the gluten from being overworked and broken.   Some of you may have experienced the dough breaking during the second proofing.  It is because the dough is over kneaded. 

The total kneading time for me is usually 15 minutes at low speeds except brioche dough with high fat percentage or dough using liquid fat which usually takes a little longer (maybe 18-20 mins).

From my experience, I found that high hydration dough with high percentage of fat will be easy to stretch and achieve a paper thin windowpane stage.

MILK POWDER 

Why do I use milk powder?  
  1. Milk or milk powder will enhance the flavour of the bread and makes the bread texture softer due to the fat content of the milk. 
  2. Milk powder is shelf stable and you can have it anytime when you want to use.  Unlike liquid milk you need to finish within a certain time before it spoils.
KNEADING TIME

For kneading, please regard the timing provided as an indication only. It is only meant as a guide.  Timing may differ depending on the brand of flour and electric mixer used. The protein content may vary from one brand of flour to another.

FLOUR

The right flour plays a very important role in bread making.   To achieve fluffy, soft and light bread, I used Japan High Gluten Flour in most of my bread baking.  The protein content is around  12 - 13%.

HYDRATION

The liquid measurement given is also a guide.  It is advisable to always reserve some liquid and not add it all in one go.  This would give you the opportunity to adjust if necessary. If dough is too dry, add the reserve liquid one tablespoon at a time until the right consistency.  This is because each flour absorbs water and hydrates differently. 

PROOFING

Please note that the proofing timing may also vary depending on your climate, environment, flour and your starter. 

If you are unable to judge by just looking at the dough, you can do the finger poke test:

Proofing:
  1. Lightly press the side of the proved dough with your finger.  If it bounces back immediately without any indentation, it means the dough is under proved and needs more time before baking.
  2. If the indentation stays and it doesn’t bounce back, it means it has been over proved.
  3. If the indentation slowly bounces back and leave a small indentation, it is ready to bake. 
  4. There will be a final burst of rising once the bread is placed to bake in the oven and it is called oven spring. 
WRINKLE TOP OR SHRINKING

If your bread collapses or gets wrinkled on top after removing from oven, it could be because your dough over proved during the second proofing. Please proof until the tip of the dough just reaches the rim of the pan, around 80% - 90% in size.

BAKING TEMPERATURE AND TIME

Do also note that the baking temperature and timing provided are what works for my oven and should also be regarded as a guide only. Every oven behaves a little differently, so please adjust accordingly for your oven.

    1. Hi, I think you can. Maybe your crumb will be abit tight or you may want to cut down all ingredients to 95.

      Cheers :)

    1. Hi, thank you for your interest in this recipe.

      You can add 15g of milk powder into the dough directly. Do not need to be diluted in the water. Please do not add all the water in one time, always reserve 10 - 20g aside and to be added in if needed.

      You can also omit milk and milk powder, just use water if you don't have both.

      Cheers :)

  4. Hi, thanks for the clarification. Meaning the whole recepi, only 72g of water is using ( sweet stiff starter). The main dough no water is required. Please correct me if I am misunderstanding. Thanks

    1. You are most welcome. No, you need to replace 50g of milk in main dough with water. It is part of the liquid. But, please do not add all 50g of water at one time, always reserve some eg 10g - 20g first.

      Cheers :)
