A few days ago, I was going through my normal routine of mixing up my dough in the morning. I usually do the mix, leave 30 minutes, then quick knead every 10 mins for 30 mins, then stretch and fold every hour for 2-3 hours (depending on the weather), shape and into the fridge to bake the next day.
Anyway, not long after mixing everything together, I got a phone call and had to go out immediately. I didn't get back home for about 4 hours and only remembered the dough when I saw it sitting on the bench in the covered bowl. After a mini panic, I mixed it about it a bit and decided just to shape it, put it in bannetons and into the fridge. I wasn't really sure what would happen when I baked it, but I thought it would be interesting to see.
Well, the baked product seemed absolutely no different to my normal efforts, I can't detect any difference at all in the oven spring, crust or crumb...
