How to Store Corn on the Cob

Check out the following tips and tricks for storing corn on the cob:

  • Fresh corn without preservatives, such as unfrozen corn, lasts up to 2 and a half days when kept in ideal conditions.
  • If you plan on eating the corn past the 2 and a half days, it’s best to refrigerate the ears within 2 hours of buying them to maintain their freshness.
  • Thoroughly inspect each ear for any signs of curved necks or dried-out silk. If you notice something, do not purchase that ear of corn.
  • Store un-husked ears in a plastic or paper bag, such as a grocery bag or newspaper, with the husks still attached. Then, tightly seal the bag to remove excess air and protect the corn from moisture loss.

How to Store Fresh Corn on the Cob

  • If you purchase fresh ears of corn with husks and attached green silk, you can keep them for over a week in your refrigerator.
  • Remove the corn from its plastic or paper bag before storing it, unless it is an ear of organic corn that remains un-husked.
  • To prevent mold growth on un-husked ears, keep them in a humid refrigerator at 40 degrees Fahrenheit (4.5 degrees Celsius) or colder. The corn should stay fresh for about 7 days.
  • Make sure to check on it regularly for mold growth and take out any ears that show signs of spoilage. Even a bad ear may indicate that the rest are not safe to eat.

How to Store Corn on the Cob in the Freezer

If you would like to store your corn for longer than 2 days, put it in the freezer. Here’s what you need to do:

  • Pick the ears with a good shape and intact husks. Once they have cooled down and there’s no risk of burning yourself, husk the ears.
  • Label an airtight bag with the number of ears inside and other instructions. For example, you can write 4 ears – thaw before cooking or 8 ears – do not re-freeze.
  • Place each ear of corn upright in one layer inside the bag. Make sure the flat side is facing down; it will minimize air contact and keep the ears from sticking together.
  • Freeze the corn on the cob until ready to use.
  • Thaw the corn by running cool water over the bag or leaving it out on a counter at room temperature for a few hours, depending on which option is more convenient for you.
  • Be sure not to leave your thawed corn sitting out again until it has reached 40 degrees Fahrenheit (5 degrees Celsius) since it can potentially lead to the growth of harmful bacteria that causes food poisoning.

How to Blanch Corn on the Cob

Freezing is best for long-term storage since it locks out oxygen and slows decomposition. But the best way to freeze corn on the cob is by blanching it; it will give the corn a richer flavor. Here’s what you need to do:

  1. Prepare a bowl of ice-cold water by storing it in the fridge. Otherwise, you can use tap water and cool it down by adding ice cubes.
  2. Clean the corn by running it under cold water; this helps get rid of any dirt.
  3. Remove the husk and corn silk to shuck the corn. If you can’t do it by hand, remove the bottom part, pop the corn in the microwave, and turn up the heat for 30 to 60 seconds.
  4. Prepare a pot of boiling water.
  5. Carefully insert the corn cobs using tongs and leave them to boil for 5 to 7 minutes.
  6. Transfer the cobs to the ice-cold water and keep them there for the same amount of time as boiling. It prevents the corn from getting cooked and maintains its current texture.
  7. Remove the corn kernels from the cob using a sharp knife.
  8. Transfer the corn kernels to resealable freezer bags, label them, and store them in the freezer.

How to Freeze Corn on the Cob in the Husk

You can freeze fresh corn on the cob in its husk, but make sure you wear some protective gear before shucking it. Here’s what you need to do:

  1. Wear thick gloves and put newspaper or paper bags on the floor where you will be working. This will help reduce messes if any of the kernels fall off while removing the husk.
  2. Shuck the corn by lifting the end that has the stem; this will help remove any of the silk attached to it. Be careful not to pull too hard on the ear because you might also pull off some of its kernels in addition to tearing apart its husks.
  3. Once you clean the entire corn, cut off the other end and soak it in water for 15 minutes.
  4. Remove the husks and dry them thoroughly. You can hang them up to dry or put them on a plate with paper towels underneath to help absorb moisture.
  5. Wrap each ear of corn individually using aluminum foil and place inside resealable freezer bags. Label the bag with the date and cook from frozen.
