I received KitchenAid Automatic Milk Frother Attachment to test. You can easily attached this to the KitchenAid Semi-Automatic Espresso Machine. Just for your information, in case, you don’t know. You can’t use this milk Frother attachment as a standalone. It really must be attached to the espresso machine to use. I found that it’s so easy to use and clean. All you have to do is clean it first then add the milk and attach the attachment to the espresso machine. I love how easy it was to use this frother attachment. I made some delicious hot cocoa with this milk frother. You are easily able to adjust the foam adjuster to get the feel that you want. Overall, a really nice attachment to use with the espresso machine. I really love how you can detach it and store it in the fridge when you aren’t using it since it holds the milk.
