Butterfly Pea Flower Soft Sourdough Bread - Yudane Method

by - July 23, 2019





I was so happy with how my Sourdough Shokupan using the sweet stiff starter turned out that I am rebaking my old recipes using a sweet stiff starter method to satisfy my curiosity.  I added more butterfly pea flowers this time to achieve this vivid colour.  However, I'm guessing that the additional butterfly pea flower causes a diminished oven spring and the result is a shorter bread if compared to white bread using stiff starter. I tried it twice and got the same result.

This is my Sourdough Butterfly Pea Flower Soft Bread using a Sweet Stiff Starter. With a stiff starter, I found that the bread proofs noticeably faster.

This Butterfly Pea Flower Soft Sourdough Bread is especially soft, fluffy and moist on the first day and it lasts very well for 2 - 3 days.  It is not sour at all.

Please scroll down to the bottom for the original Liquid Starter recipe that I shared sometimes ago if you are interested in an alternate method.

RECIPE - SWEET STIFF STARTER + YUDANE METHOD

Yields:  2 Loaves in 450g Loaf Pan
Utensil:  450g loaf pan (21.3 X 12.2 X 11.5 cm  /  8.4" X 4.8" X 4.5")

INGREDIENTS:

Butterfly Pea Flower Water:
120 dried butterfly pea flowers
250g water

Yudane Dough:
70g bread flour (I used Japan High Gluten Flour)
70g boiling butterfly pea flower water

Sweet Stiff Starter:
60g sourdough starter (100% Hydration), use at its peak 
180g bread flour (I used Japan High Gluten Flour)
75g butterfly pea flower water, room temperature
30g sugar (I used organic brown sugar)

Main Dough:
70g bread flour (I used Japan High Gluten Flour)
All yudane dough (above)
All stiff starter (above)
10g brown sugar (I used organic brown sugar)
1 tsp salt
35g milk powder (I used full cream/whole milk powder)
70g butterfly pea flower water, room temperature (reserve 10g and add in later if needed) I used total 70g of water
25g butter, room temperature

Egg Wash: (Optional)
1 egg + 1 tbsp water, whisked

METHOD:
  1. Butterfly Pea Flower Water (prepare one night before):
    1. In a sauce pan, boil flower and water.  Off the fire once boiled. 
    2. Steeping for 30 - 60 minutes,  strain to get the blue water.
  2. Yudane (prepare one night before):
    1. Add bread flour in a bowl, pour the boiling flower water and mix well with spatula or spoon until no dry flour.
    2. Cling film and place in the fridge for at least 4 hours or overnight.  
    3. Take out from the fridge 30 minutes before using to return to room temperature.
  3. Sweet Stiff Starter (prepare one night before)
    1. In a bowl of stand mixer, dilute starter with flower 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. The starter should look smooth and round dome.  It shouldn't collapse.
  4. Main Dough:
    1. Put all ingredients (except butter) into a bowl of stand mixer.  I usually torn the stiff starter and yudane dough into pieces 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.  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.
  5. 1st Proofing/Resting:
    1. In the same bowl, let the dough rest for 30 - 60 minutes. Keep it covered with clingfilm or use a lid.  This dough I rested for 45 minutes at 29C room temperature and the dough rose quite a lot in 45 minutes.  (I did not find any big differences of 30 mins to 60 minutes rest.  So, please follow your schedule).
  6. Shaping:
    1. Transfer the dough to a clean floured surface then divide into 2 equal portions.  Please use a kitchen scale if you want to be exact.
    2. Form each portion to a ball.  Flatten with rolling pin.
    3. Fold right to centre and fold left overlap it.  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 the prepared loaf pan.   
  7. 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 29C - 30C.  The duration of proofing depends on your ambient temperature and starter.
  8. Baking:
    1. Preheat oven at 190C (top & bottom heat) for 10 - 15 minutes.
    2. Brush with egg wash (optional) and bake in a preheated oven for 25 - 30 minutes, or until golden brown.
    3. Remove bread from oven and let them cool on rack completely before slicing.

Butterfly Pea Flower Soft Sourdough Bread

Butterfly Pea Flower Soft Sourdough Bread

Butterfly Pea Flower Soft Sourdough Bread


Butterfly Pea Flower bread seems to be the trend now.  I guess I am joining the trend too now since there is an abundance of this flower growing in our garden.  I am a little bit "kia soo" and added a lot of flowers to yield this beautiful deeply colored bread. The flower does not give any real flavour to the bread but it just looks pretty.

This Butterfly Pea Flower Soft Sourdough Bread is especially soft, fluffy and moist on the first day and it lasts very well for 2 - 3 days.  There is slight mild sourness taste.

RECIPE - LIQUID STARTER + YUDANE METHOD

Yields:  1 loaf in 450 Loaf Pan

INGREDIENTS:

Butterfly Pea Flower Water:
60 - 80 dried butterfly pea flowers
250g water

Yudane:
50g bread flour (I used Japan High Gluten Flour)
55g Boiling butterfly pea flower water

Levain - 190g (ratio 1:3:3):
30g sourdough starter (100% Hydration)
85g bread flour
85g butterfly pea flower water

Main Dough:
205g bread flour (I used Japan High Gluten Flour)
All yudane dough (above)
190g levain (above)
30g brown sugar (I used organic brown sugar)
3/4 tsp salt
3 tbsp (30g) milk powder
25g butter, room temperature
85g - 95g butterfly pea flower water

Utensil:   
450g Pullman Loaf Pan (20 cm X 10 cm x 10 cm)

METHOD:
  1. Butterfly Pea Flower Water (prepare one night before):
    1. In a sauce pan, boil flower and water.  Off the fire once boiled. 
    2. Steeping for 30 - 60 minutes,  strain to get the blue water.
  2. Yudane (prepare one night before):
    1. Heat up 55g flower water in a small saucepan until boil and off the fire.
    2. Immediately add in bread flour mix well with spatula or spoon.  The dough is slightly dry when you mix it and eventually it will all come together. 
    3. Transfer to a glass container or a bowl and cover. Place in the fridge for at least 4 hours or overnight.  
    4. Take out from the fridge 30 minutes before using to return to room temperature.
    5. I made the yudane dough 4 hours before and left it outside instead in the fridge. It works too.
  3. Levain (prepare one night before):
    1. Mix all ingredients in a jar and cover.  Make sure the butterfly pea flower is at room temperature.
    2. Let it ferment at room temperature (approximately 27-28C) overnight until tripled.  It took about 12 hours. It yields about 200g of levain.  But, you will only need 190g.
    3. Note:  If you want to prepare the levain on the same baking day, please use the ratio 1:1:1.  Let it ferment at room temperature (approximately 30C) until tripled.  It took about 3-5 hours depend how strong is your starter.
  4. Main Dough:
    1. Put all ingredients (except butter), including the 190g sourdough starter (levain) and yudane dough into the bowl of stand mixer. Using the dough hook, knead for 3 - 5 minutes (Chef Kenwood mixer, speed 2.5) until the dough comes together.  Add in butter and continue kneading for 10 - 12 minutes and reach window pane stage.
  5. First Proofing/Resting The Dough:  
    1. In the same bowl, let the dough rest for 60 minutes. Keep it covered with clingfilm or use a lid.  The dough did not rise a lot in 60 minutes.
  6. To shape:
    1. Transfer the dough to a clean floured surface then divide into 2 equal portions. 
    2. Form each portion to a ball.  Flatten with rolling pin into a dish.  
    3. Fold right to centre and fold left overlap it.  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 the prepared loaf pan.  
  7. Final Proofing:
    1. Let it proof at warm and dark place until the dough reaches the height of the pan (This one took approximately 3.5 hours at room temperature of 28C - 30C) then put on the slide-on lid. Then leave it rise for another 1 hour.  It may take longer to proof depending on your ambient temperature and your starter.
  8. To bake:
    1. Preheat oven at 190C (top & bottom heat) or 170C (fan-forced) for 10 - 15 minutes.
    2. Bake at preheated oven for 30 - 40 minutes, or until golden brown. 
    3. Remove bread from oven and let it cool on rack completely before slicing.




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.  

There are so many ways and methods of how to maintain the starter.  Below is my method of starter maintenance.  This is just for your reference. Please try and find a way or schedule that works best for you.

I bake almost everyday.  So, my starter is left at room temperature and I feed it twice a day every 12 hours at its peak when it is tripled.

Example
10.00 am - at ratio 1:10:10 at room temperature 26C - 27C
10.00 pm - at ratio 1:10:10 at room temperature 25C - 26C 

I feed a very small amount of 1g starter + 10g water + 10g flour if I am not baking, so that I will not end up with too much discard.  When I am baking, I will feed the starter accordingly to make up the quantity required by the recipe to be baked. If I know that I won't be baking for a few days, I will then feed it only once a day at 1:10:10, transfer to the fridge when it is doubled, and feed again 24 hours later.

If you do not bake daily or if you bake perhaps once or twice a week, then you may place your starter in the fridge and feed once a week.  But, you will need to refresh your starter 2 days before the baking day. There is no way around this, sourdough baking takes planning! 

How I judge my starter is healthy?  My starter usually tripled in size (or at least double) in within 3 - 4 hours at room temperature (27C - 28C) for feeding ratio of (1:1:1 = starter:water:flour)

When is a starter at its peak?  My sourdough starter is usually at its peak when it is tripled in the jar. The surface of my starter looks bubbling and uneven.  It usually stays at its peak within 30 - 60 minutes before it starts to reduce/fall.  

Why use starter at its peak?  This is when the starter is most active and it will result in a better rise for your bread in general.  By the way, you can use when it is doubled/before its peak too.  But, not it starts to fall.

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, thank you for your question. Sometimes I do. But, sometimes I don't when I busy. I have seen some articles claimed that taking too much of the green base is toxic. However, there is no scientific proof yet.

  4. Hi, I would like to bake a pandan soft sourdough loaf, do you think it is possible to replace the blue pea flower water in this recipe with pandan juice/paste?
    Btw, I did try the orange cranberry soft sourdough loaf the other day, other that underbaking it, we love the taste. Thanks for all the soft bread recipes using sourdough. I hope you will share more recipes in the future. :)
    Thanks!

    1. Hi, thank you for your question. Yes, it is good idea to make pandan bread. But, bear in mind sometimes Pandan may not work well with long fermentation. The smell will change to become like cheese.
      If you want to try, you can replace blue pea flower water with pandan juice except for the Yudane. Please use boiling water instead as Pandan juice will turn to brown colour when you boil it.

      Cheers :)

  5. Hello! Right now, I don't live in an environment where I can start a sourdough starter (my house is too cold!!) and I was wondering if this can be adapted with yeast. If so, what would you recommend the measurements be? If it can't, no problem! Would love to make some of your sourdough soft bread recipes with yeast.

    1. Hi, thanks for visiting Bake with Paws. I have plenty of yeast bread recipes in my blog too. Just search under categories.

      For this bread, please use this recipe and just replace milk or water with Butterfly Pea Flower Tea.
