Okay, so I’ve been on a mission to level up my mashed potatoes. I've heard of people adding stuff like miso paste or horseradish, but what's the weirdest or most random thing you've tried? I'm tempted to add a splash of soy sauce next time—too crazy, or genius? Let's hear your odd but awesome mash-up ideas!
