Purple Carrot Open Crumb Sourdough Bread


I have been using Purple Carrot to bake Purple Carrot Soft Sourdough Bread and the colour turned out to be beautiful. I was thinking I should try it on an open crumb sourdough bread too.  Unfortunately,  I was unable to achieve a good oven spring using carrot puree.  I thought that maybe I added too much carrot puree.  So, I tried it a second time with a reduced amount of carrot puree.  It was slightly better but still lacking oven spring.  I guess it must be the carrot pulp that causes the bread to become dense.  So, I decided to use carrot juice instead and finally, that worked! I got oven spring.  However, the crumb still not as nice as my previous bakes and I am wondering if there is some property in the carrot that causes the bread to be dense.  Please let me know if you know the answer.

Please read the below notes before baking for beginner.

ROOM TEMPERATURE & BULK FERMENTATION
Room temperature in your kitchen plays a very important part in sourdough baking.  It will affect the dough temperature and eventually affect your fermentation time. Warm ambient temperature will contribute to a shorter fermentation time while a cooler room will extend fermentation time.  A longer fermentation duration allows you to have more time to develop the gluten structure . Therefore, high fermentation (warm ambient) doesn’t allow you to work the dough as well.   I learned this from Janet The Soprano

29C – 30C was my kitchen ambient temperature (without air-conditioner)
24C - 26C was my kitchen ambient temperature with the air-conditioner turned on.

I turned on my air-conditioner when I added in levain. My ambient temperature was 24C - 26C during bulk fermentation.  Bulk fermentation is when you let your dough rest after adding in the levain and before you shape your dough.

Usually the best bulk fermentation time that worked for me is 4 - 5 hours at 24C - 26C ambient temperature, provided my starter is healthy and active.  At the end of bulk fermentation, my dough would have increased 40% - 50% in volume. 

SOURDOUGH STARTER
A healthy starter is very crucial as advised by Baking with Gina.  It is advisable to feed your starter daily if you want nice big crumb bread that rises nicely and to use the starter (levain) at its peak.

If the mother starter is not strong, the bread dough will not rise much even though the starter is used at its peak.

SALT
You may wonder why most of the recipes asked to add salt after autolyze and adding levain.  Salt will tighten the gluten and make it harder to stretch.

Recipe - Purple Carrot Open Crumb Sourdough Bread 

Total flour:  300g + 30g (from levain) = 330g

INGREDIENTS:

270g bread flour (I used Japanese high gluten flour) - 90%
30g whole wheat flour - 10%
224g purple carrot juice water (reserve 10g for salt) - 77% final hydration
6g sea salt - 2%
60g levain (sourdough starter - 100% hydration) – 20%

Purple Carrot Juice:
65g steamed purple carrot (from 1 medium carrot)
210g water 

Banneton (proofing basket)'s size - 6.5" oval shape

METHOD:
  1. Feed starter - Feed ratio of 1:1:1, keep at room temperature (28C – 30C) and wait until tripled, around 2 – 3 hours.
  2. Purple Carrot Juice - Peel, cut and steam the purple carrot for about 15 minutes.  Blend the steamed carrot with water.  Strain the carrot pulp through a sieve.  You will get roughly about 224g of juice.  If not enough, just top up with water.   The reason I steam the carrot is to prevent the carrot from oxidise and preserve the purple colour.
  3. Autolyse - Mix flour and carrot juice, stir until there is no more dry flour with a spatula then by hand.  Or use a stand mixer with paddle attachment for 2-3 minutes at low speed.  Cover and leave for 1 to 2 hours.
  4. Levain - Wet your hand, add 60g sourdough to the dough and hand mixing until incorporated, about 3 - 4 minutes. Or use a stand mixer with hook attachment and knead for 6 to 8 minutes.  I used hand mixing for this loaf. Cover and rest for 30 minutes.
  5. Sea Salt - Dilute sea salt with the balance of 10g carrot juice.  Pour on top of the dough, use hand to mix in the sea salt water.  It takes about 5 minutes until it is fully incorporated.  Cover and rest for 15 minutes.
  6. Stretch and Fold (S&F)  - Perform 1 set of S&F.  Please see the diagram.  Cover and rest for about 30+- minutes or until the dough spread.  Please feel and watch your dough and not the clock.
  7. Lamination -  Please watch the video below. Lightly mist the counter top with water and wet your hand.  Pull from centre out to form a rectangle shape.  Pick up one edge and fold into the center.  Pick up other edge and fold into the center over first section.  Fold the top down half way.  Fold the bottom up.  Put dough in a clean dish.  Cover and rest for about 30+- minutes or until the dough spread.  Please feel and watch your dough and not the clock.
  8. Coil Fold 1 - Fold dough in the dish. Cover and rest for about 30+- minutes or until the dough spread.
  9. Coil Fold 2 - Repeat the same.  Cover and rest for about 30+- minutes or until the dough spread.
  10. Coil Fold 3 - Repeat the same.  Cover and rest for 60 - 90 minutes or until the dough rise about 40 - 50%. 
  11. Shape - Please watch the video below. Flour the counter top.  Shape and transfer to a heavily flour banneton.  
  12. Proof - Proof at room temperature for 15 minutes.  
  13. Retard - Then retard overnight in the fridge for 12 - 16 hours.
  14. Baking
    1. Preheat oven, with the dutch oven at 250C for 30 minutes before baking.  
    2. Take bread dough out from the fridge, invert onto a parchment paper and scoring (please watch video).  Immediately transfer the dough with the parchment paper to your preheated dutch oven.
    3. Lower the temperature to 230C (fan-forced) and bake with cover on for 20 minutes.  Remove the cover and lower the temperature to 220C (fan-forced), continue bake for another 10 - 15 minutes.
    4. Remove bread from oven and dutch oven. Let it cool on rack completely before slicing.
Note:  
Usually 3 coil folds should be enough.  But, sometimes you may need extra coil fold if your dough is spread and not enough gluten develop.
