We've all been there - you're in a rush, or you get distracted, and before you know it, your mashed potatoes have been sitting out for hours. Don't panic! If you've left them out for less than two hours, they're probably still safe to eat. But, if it's been longer than that, it's best to err on the side of caution and toss them.
So, what can you do to avoid this predicament in the future? For starters, make sure to label and date your leftovers, so you know exactly how long they've been sitting in the fridge. And, if you're planning to store them for an extended period, consider using shallow containers to help them cool down faster.
