Spiced Pumpkin Sourdough Bundt Bread


Have you ever tried to transform a cake into a bread? Well this is what I've done with this experiment. I took a bunt cake recipe, where the rising agent was baking powder and baking soda and do some adaptations to rise it exclusively with sourdough.


The first, I baked the no sourdough version to see if I like it. As it resulted in a delicious cake, I adapted the recipe so I give up on baking powder and baking soda and introduce only sourdough. The result was absolutely impressive and I know for sure that I'll do this more often in the future.

Before launching myself into such an experiment, I did a bit of research on google to see how others have done it. Unfortunately, most of the recipes I found had sourdough in the title but actually it was not the main rising agent of the cake because they were adding baking powder. In this case, the sourdough mentioning looked faked to me because sourdough was used just like an extra ingredient without having any significant importance in the rise of the cake.

I had some experience with rising sweet bread in the past, see Romanian Sourdough Sweet Bread (Cozonac cu maia) but not with bundt cakes/bread where the dough is more hydrated, being in fact a batter.

My first concern when adapting the recipe was the preservation of the ingredients during the rising time. For a classical bread, a dough made from flour and water can stay at room temperature during 1 day without any problem, but when we are talking about adding ingredients like puree, eggs, things are changing as their perishable property needs to be considered. What I did to avoid this was to let the mixed butter (already put in the pan) in the fridge overnight. This benefitted from a cooling time (reduced unwanted bacteria development) while increasing the flavours. There is another aspect that balance this. The introduction of the sourdough adds a level of acidity in the batter that contributes to a better preservation of the ingredients. That's why, let's say that for this version I was extra cautious because in the case of the Cozonac cu maia the rise was at room temperature with no risk of altering the healthiness of the ingredients.

Taking into account the above considerations, I think that there is no risk if the rise is done at a room temperature over the day without needing to retard the batter in the fridge.

For this recipe I used stiff starter, at 50% hydration. Why? Simply because stiff starter has low acid taste and is more appropriate for sweet breads rather than 100% hydration starter.

I am sure you ask yourself which one was was better? With sourdough or without?

I found the sourdough version more soft, moist and flavoured than the one without sourdough. However the differences in taste I think they were minor, they were more just nuances. As for healthiness, I think there is no doubt which one is better.

There are differences in the methods of doing the 2 versions. The sourdough one takes longer and cannot be done in one shot like the no sourdough version can be. If you are a sourdough geek like me, most probably you'll find worthy to spend more time and make the sourdough version. If you are not, go for the no sourdough version.

Please also note that the temperature of baking is different between the versions and I can tell you that if you increase the temperature of the oven for the one with baking powder you might experienced cracklings. Otherwise, in the aspect they look almost identical. Maybe just the version with sourdough is lighter as colour due to the sourdough addition. I didn't photograph the no sourdough version but they are very similar as aspect.


Bellow are the 2 versions, which one are you tempted to try?


Sourdough version (the one presented in the video):

Ingredients:

  • 550g all-purpose flour
  • 500g roasted pumpkin puree
  • 4 eggs (~240g)
  • 150g stiff sourdough starter (50% hydration)
  • 150g jam (sugar can be used instead too)
  • 3 teaspoons cinnamon (~12g)
  • 2 teaspoons ginger powder (~10g)
  • 1 teaspoon nutmeg (~5g)
  • 100g vegetable oil (I used corn oil)
  • 5g salt
  • 2 teaspoons vanilla extract


Directions:
  1. [Day 1, Saturday, 18:00] Scaling. Start by scaling all ingredients, as they are many, you might miss some if you do not measure them at once.
  2. Mix the flour, with pumpkin puree and eggs just until well combined. Let the butter for 1 hour at room temperature.
  3. [Day 1, Saturday, 19:00] Add the sourdough starter and salt. The starter is stiff and you may want to cut it in pieces for better incorporation. Mix until well combined. Let it relax for 1 hour.
  4. [Day 1, Saturday, 20:00] Add spices, jam, vanilla, and oil. With the mixer on, add these ingredients one by one and mix until well incorporated. Especially for oil, you need to add it in steps to be well introduced in the batter. Let it relax for 3 hours.
  5. [Day 1, Saturday, 23:00] Put the batter into the pan. But before that, season well your pan with butter and almond powder to avoid sticking to the pan. After you put the batter into the pan, cover it and place it in the fridge overnight. It will rise a bit in the fridge but not a lot.
  6. [Day 2, Sunday, 8:00] Remove the pan from the fridge and keep it covered in a warm place up until the rise reach the top level of the pan. When it is almost ready, preheat the oven at 180ºC.
  7.  [Day 2, Sunday, 10:00] Bake it for 45 minutes or until the core reaches 95ºC, or until a wooden stick wood comes out clean.
  8.  [Day 2, Sunday, 10:45] Let it cool for about 15 minutes before unmoulding it. If you can touch the pan without getting burned, it is ready. After unmoulding, continue to let it cool until it reaches the room temperature.
  9. [Day 2, Sunday, 12:45] Now you can slice the bread/cake and enjoy its beautiful flavours and aromas.



    No sourdough version

    Ingredients:

    • 560g all-purpose flour
    • 500g roasted pumpkin puree
    • 4 eggs
    • 1 teaspoon baking powder
    • 1 teaspoon baking soda
    • 150g jam (sugar can be used instead too)
    • 3 teaspoons cinnamon (~12g)
    • 2 teaspoons ginger powder (~10g)
    • 1 teaspoon nutmeg (~5g)
    • 175g vegetable oil (I used corn oil)
    • 5g salt
    • 2 teaspoons vanilla extract


    Directions:

    1. Mix all dry ingredients in a bowl.
    2. In a standing mixer bowl add the eggs, pumpkin puree, jam and vanilla essence, one by one and mix in between additions.
    3. Add dry ingredients in the mixer bowl while continuing to mix, one tablespoon at a time. Be sure you have your mixer set at a lower speed to avoid dusting your kitchen
    4. Add the oil, a bit at a time while continuing to mix. It is ready when all ingredients are well incorporated.
    5. Bake in the preheated oven at 160ºC for 50 minutes or until the core reaches 95ºC, or until a wooden stick wood comes out clean.
    6. Let it cool for about 15 minutes before unmoulding it. If you can touch the pan without getting burned, it is ready. After unmoulding, continue to let it cool until it reaches the room temperature.
    7. Now you can slice the bread/cake and enjoy its beautiful flavours and aromas.


    This, the no sourdough version is originally inspired from Julie Anne Hession  - Beautiful Bundts: 100 Recipes for Delicious Cakes and More but with numerous adaptations to make it healthier.
