I'm looking for recommendations for a stand mixer. I'd like it to be strong enough to make a batch of challah with 5 lbs. of flour to be able to do hafrashat challah. I'm told most mixers are not up to this task. Every I speak to refers me to the Bosch Universal Machine, but I am hesitant to buy German. Does anybody have experience with other mixers that are up to the task? Does anybody have any experience with the Cuisinart 7 qt. mixer?
