Why can you leave a raw potato out of the fridge without spoiling but not a cooked/boiled one?
In: Chemistry
First, a raw potato outside of the fridge absolutely will spoil, especially if the weather is warm and humid. There’s no feeling quite like clearing out the cabinet, looking for whatever’s making that horrible smell, and having your hand go *into* a rotten potato.
It takes less time for a cooked potato to spoil because cooking the potato turns starches into sugars, which are more hospitable to bacteria and fungi, and also often involves piercing the potato’s skin, which helps protect the potato from said bacteria and fungi.
