How long does cooked corn on the cob last?
Of course, the shelf life of cooked corn on the cob is shorter than that of fresh corn on the cob, but how long can you still enjoy it after cooking it? There are a few factors that can affect the answer to this question, including how it’s stored, whether it’s been seasoned, and whether it’s still on the cob or has been removed.
