In every bread book I've read, it's always suggested to retard dough during while its proofing (with the exception of pain a l'ancienne). Is there any reason one shouldn't do this during bulk fermentation? I imagine the yeast population is a lot smaller at that point, so It may not have as drastic of consequences. Also, since the cold makes dough much more elastic, it may have a negative effect on doughs that need folding. Has anyone tried this?
