1:2:3 loaf with 20% wholewheat spelt and yeast water
My twist on this was to use Rosie, my yeast water culture, for approximately 50% of the liquid. Saturday morning refreshed some of my starter and left it to do its thing all day. Saturday evening I fed it again and left it overnight. At the same time I mixed up 50 g flour and 50 g yeast water and left overnight. Late the next morning I added the rest of the liquid to the YW preferrment and the flour and autolysed for 45 minutes. Added levain and salt. I only managed 3 sets of slap and fold / stretch and folds before it had doubled.
