With this method, your corn will stay farm-fresh for about three to five days. Sometimes a whole week, if you started with really fresh corn. After that, the sugars start turning to starch, and it’s less candy-sweet. But it won’t be a wrinkled mess.
If you need to buy corn super early for a weekend cookout, do this on a Wednesday. It will be perfect by Saturday. That’s a game-changer for meal planning. You can actually relax instead of panic-eating corn for three days straight.
