Soaker - I don’t have wheat flakes so I’ve used something different that doesn’t need soaking for hours(recipe calls for wheat flakes) 100g Wheat Flakes (Weet-Bix)
I mixed everything by hand, very sticky/messy to knead but all goes well at the end, Bulk Fermented until almost doubled. Was very cold that time, left it on the counter overnight @ 14c deg room temperature about 11pm to 8am and probably temperature drop a bit more over night. Shaped it in the morning and let it proof in the banneton for another 3 hours @ 15c to 16c deg room temperature, 20 hours cold retard @ 4c to 5c deg.
