Isn’t it frustrating?! So Nathan Myrvold’s – Modernist Bread, in addition to so many website searches including KitchenAid’s says “climbing happens”.
One way to reduce the climb is to not overstuff the bowl, limit the amount to a batch size of 2-3. I take the batch size of 4 but mix in two phases, 1/2 at a time. You can do this by creating two 1/2’s of all the ingredients – measure and prepare all the units as if for 4 but each time you go to add them to the mixer, only use 1/2. I’m shooting a video on this today and will post.
