One of the benefits of owning a KitchenAid is that they make a lot of really cool add-ons for their stand mixers. The mixers and attachments have both changed and improved over the years. However, KitchenAid has kept the power hub consistent. This means that even if you have a 30-year-old KitchenAid mixer handed down from your mom’s wedding registry, you can buy the brand-new ravioli maker attachment you want and it’ll fit right in.
