When a potato gets cold—like, really cold, below about 45°F—something weird happens inside. The starch in the potato starts turning into sugar. It’s a survival thing for the potato, but for us, it means a sad, sweet-tasting spud.
You might not notice it raw, but the moment you fry or roast that chilled potato, it can turn dark brown or black and taste a little like candy. Not the good kind—the kind that makes your fries taste off and your roasted potatoes look like they’ve been through something.
I remember one Thanksgiving when my aunt proudly made mashed potatoes from a bag she’d kept in the fridge for two weeks. They were gray and sweet. We all smiled and said, “Mmm, interesting texture,” but inside we were mourning the buttery, fluffy clouds we deserved.
