hi, realy appreciate your post, i wonder if you could tell me how much activity your culture has when put into the dough, mine was at the pick of its activity or close on the way up and the preferment was well ready after 15 hours what didnt please me, i put exactly as much as u indicated, i dont know, the temp wacs 70 or a bit lower maybe 68 and after 12 hours of proofin the final mix it was double the size or a bit more but didnt fall so i am going to try it right now, is there any point of punchin down now when the dough balls are after 12h proof an leave it to rise 1.7? thanks, adam
