Hi Folks. I have a Kitchenaid stand mixer. I bought it to knead whole wheat bread dough. When I use it to knead dough, the dough climbs up the dough hook. It only takes thirty seconds and I must stop the mixer and scrape the dough off the hook with a rubber spatula. I've cleaned the dough hook carefully. I've put shortening on it. I've tried using one cup of flour or four cups but nothing works to stop it. What do you suggest? Thank you all!
