120: האם אפשר ללוש בצק לחם יותר מדי ביד? (שמרים) - Bake with Jack

I'm SURE (well, pretty sure) this would have been different with wholemeal flour... It is very possible to over knead a bread dough in a machine, I've been there: Sticky dough without any evidence of the strength and structure that built up along the way. But is it possible to do by hand and if it is, how long will it take to get there?
