Thanks to everyone who responded before. You've given me some really valuable opinions. Please bear with me on this subject just a little longer... I was trying to duplicate a friend's recipe for shea souffle. Her's is as light as air -- mousse-like, not cream-like. (I can't find the words to describe her consistency! Airy, mousse, like a cloud, almost foamy, but not foam...) I followed her recipe ingredients with one exception... she used unrefined shea butter, and I used refined. She had used her Kitchenaid, and I had used my handheld. Mine turned out nothing like her's. Mine is like a cream. The only thing I can think that made such a difference was her KA mixer. In shopping around, I've noticed that the KA and the Hamilton Beach (which is much cheaper) use a single beater which looks like a whisk. Do you think that this is the secret to getting the consistency I've described? The other brands of stand mixers appear to use two beaters like my handheld does. I did not know about the heat factor of a handheld. But I'm really wondering if it is the whisk that sets the KA apart and gives you the really fluffy results.
