I bought corn on the cob already pulled from their husks inside of a sealed bag that's been outside how long are they good for

I never buy shucked corn for the reasons set out below. I roast it in the husks either on the grill or in the oven. The silks actually come off easier after roasting. I buy in quantity when it is at peak. I cut it off the cob and freeze it. Then I use the cobs and residual milk to make corn chowder. There are lots of great tricks for cutting corn off the cob. One of my favorites is to position the cob on the center of a Bundt pan & run a knife along the cob. The Bundt pan catches all the kernels. No single use gadgets need be purchased. You can also place a high ball glass upside down in a mixing bowl and proceed the same way.

Agree. Cook immediately, for eating, use in other dish, or freezing.
By the way, frozen food is usually of top quality....picked at peak ripeness, blanched and/or frozen immediately.

Once picked, fresh corn quickly changes from sugar to starch. Many believe that corn is ideally cooked a couple of hours after picking.

Clearly, the kernels you have purchased have been off the stalk for much longer and did not benefit from sitting out in the sun.

I would cook it ASAP.

There is definitely the option of freezing it although once defrosted it might not be much better than a box of Birdseye that you'd find in the frozen veggies section of your nearby supermarket due to the produce stand's poor handling.

While you do not mention how much you purchased you could cook what you'd use immediately and freeze the rest. Depending on the quantity, you may want to portion out what you will freeze into single servings or more manageable sizes.

Best of luck.
