In general, chestnuts can last for up to 2 weeks in the fridge, but that's only if you store them in a cool, dry place with some air circulation. It's like they need their own personal space, you know? If you don't give it to them, they'll start to mold and rot, and trust me, you don't want that.
But here's the thing: not all chestnuts are created equal. Some varieties, like the Italian or Spanish ones, can last longer than others. And if you roast them before storing, they can last even longer - up to 3 months! That's like, a whole season of chestnut-eating bliss.
Now, I know what you're thinking: what's the best way to store these bad boys? Well, the answer is simple: in a brown paper bag or a breathable container. You don't want to suffocate them, or they'll start to steal each other's oxygen (okay, maybe that's a bit of an exaggeration, but you get the idea). Just make sure to check on them every few days, or they might just surprise you with a funky smell.
