Think of your fridge as a cool, damp cave. That’s exactly where chestnuts want to be. Simply place them in a perforated plastic bag—you know, the kind you get apples in at the store.
Why perforated? Because chestnuts need to breathe. Seal them up tight, and they’ll suffocate and get moldy. Leave them totally open, and they’ll dry out and become rock-hard.
This simple method will keep them happy for about two to three weeks. It’s like putting them in a gentle hibernation. Just remember to peek in every few days and remove any that feel soft or look fuzzy—mold spreads fast in a crowd.
The “Paper Bag” Trick (When You’re Feeling Fancy)
Want to get a little extra careful? Try the paper bag method. Toss your chestnuts into a plain paper bag, then tuck that bag into the crisper drawer of your fridge.
The paper absorbs extra moisture while still letting them breathe. It’s like giving them a tiny, breathable tent instead of a plastic jacket. This can stretch their shelf life to nearly a month.
How to Store Chestnuts, Both Raw and Cooked
But here’s a warning: do not wash them before storing. Water is the enemy. If they’re dirty, just brush them off. Washing introduces moisture that invites mold to the party.
