how to freeze sweet corn

To freeze sweet corn, here is a reliable step-by-step method:

1. Husk the corn and remove all silks from the ears.
2. Bring a large pot of water to a boil.
3. Add the corn ears to the boiling water and blanch:
   • Small ears: 7 minutes
   • Medium ears: 9 minutes
   • Large ears: 11 minutes
4. Immediately transfer the corn to a large bowl of ice water to cool for about the same amount of time as the blanching.
5. Drain and pat the corn dry.
6. Cut the kernels off the cobs using a serrated knife, ideally over a bowl to catch the kernels.
7. Place the kernels in airtight freezer bags or containers. Remove as much air as possible before sealing.
8. Label the bags with the date and freeze.

For freezing whole corn on the cob without cutting off the kernels, follow the same blanching and ice bath steps, then wrap ears individually in plastic wrap or place in freezer bags before freezing. If you want a quicker method without blanching, you can cut the kernels off raw corn and freeze them immediately, but for best quality and longer storage, blanching is recommended. Frozen sweet corn is best used within 8 to 12 months for optimal flavor and texture.
