Catherine, I’m using the new Classic formula. Previously I was able to do a 4 loaf batch in my KA Pro 5; I think was because the porridge was added earlier and the looser, wetter dough was easier on my mixer. But with the new formula with the kneading mainly done pre-porridge, my mixer can’t handle such a big batch of stiff dough. I gave it some rests but it shut down. I know now (!) that you recommend doing the mix in two batches on a KA. But is it possible/advisable to add my porridge earlier and do the kneading then in one 4-loaf batch? Hope this makes sense.
