this bread is a bit experimental. I tried to revigorate the starter, 
so it grew to quite a big volume over the last few days. That
went into this bread without much 'proving' time, because I didn't
plan it right and it was too late in the night. The final dough 
rested maybe 2 hours. The flour ratio is otherwise about my usual 1:1.

The bread looks nice, tastes okay, but is a bit chewy.
It really needs the extra time. Lesson learned, i guess
