Double-fed sweet levain bread

I am struggling for a while to get a bread with a good structure inside and nice holes. Not that this would give me my perfect bread but it is a challenge with myself. I blamed the flour, I blamed the recipe and a lot of other elements. This time I manage to get my dream. A nice airy and chewy crumb and an incredible flavor. When I took the lid off, I was disappointed to not see a clear score but when I cut the bread.... this was a revelation. Comparing to the first 3 breads of Ken Forkish, this one had a different method: bulk fermented at room temperature and proof in the fridge over night. The next day, when I have opened the fridge I was shocked ... it had raised so much that it was almost over the banneton. So, immediately I had to turn on the oven and wait to be ready to bake.

Great recipe, great bread! Strongly recommended.


Ingredients:

First feeding:

• 17g sourdough (100% hydration)
