@Torah613 a kitchenaid can’t make 5lb of challah. the bowl isn’t big enough and I don’t think the 6qt 600 hundred series can handle it. But the 4.5 qt can definitely handle 7 cups of flour so aprox 2.5 lbs?
We have a kitchenaid which is used often. I’m not a fan of our Bosch. The bowl has a post in the middle and very hard to clean. But we do use it occasionally.
And our Bosch is over 20 years old which is normal for a basch.
