Do you have a before picture? This looks so satisfying

idk where you've heard that but I've been eating handmixer-beaten mash for my whole life. It has gotten a little gummy before but what's supposed to happen then? Am I gonna die from sticky potato??

Edit to say: I have googled this because it sounded so wild to me lol. Yes you can overmix your potato. But as long as you use the right kind of potato and only mix until you have your desired consistency, it will be fine. Add some butter, milk and nutmeg and you're good to go. No need for a chunky, hard to do mash.you can definitely tell whats happening by just looking at what you're doing, and stopping when you've mixed enough. It's just as easy as mixing cream. Yeah you might overmix, and if you do you get butter, but really once you've got the hang of it there isn't any reason to not use a hand mixer
