Shallower bowl or longer dough hook for Kitchen Aid 7qt Stand Mixer? I have a 7qt lifter style kitchen aid stand mixer and use it often to make bread and pizza doughs.

Generally works great for very large batches, but I find that either the 7qt bowl is too deep or the dough hook isn't quite long enough and smaller batches end up with more than half of the ingredients hanging out below the hook.

Are the 6 qt bowls compatible, but shallower?   Is there a longer dough hook available?   Any suggestions?
It is most likely that your bowl is simply too big for the recipe batch size.
I habe a 5qt KA Pro Model lift bowl style.

For Easter 2018 I made half a batch of my buttorn roll recipe. That size batch called for only 1-1/4 cups of A-P flour and I quickly learned that I was going to make those for dinner, I was going to have to mix then knead the dough the old-fashioned way = by hand.

Turned out great and added a note in my cookbook to avoid the extra cleanup.
