Hamburger, for the most part, is funky here. It's got a sticky, gelatinous texture and a funny taste. Regular, unground beef is fine. So, what to do? Get an attachment for the KitchenAid to grind my own. Going to be something new for me to do. Oh, and a new whisk, since mine is falling apart. Of course, more things I cannot use until we get our stuff.
