A small mistake last bake and Pulla Zilla!
Wow, this is the biggest rise and oven spring I have EVER had! Now the working part of my peel measures 8"x14" and this loaf filled most of it using 460 grams of flour! Best pulla ever, with a soft almost shreddalble crumb.
Normally, I will do a sponge of liquid levain, sugar, egg, flour and scalded milk infused with cardamom. After this got happy, I would put it in the fridge at bedtime, remove it in the morning and mix after about an hour of warm up.
