What Is The Best Corn To Freeze?

Before we discuss the best ways to freeze corn, let’s first find out what is the best corn to freeze.

According to the Purdue University Cooperative Extension Service, we can freeze sweet corn varieties without issues.

To name some examples, Bodacious and Incredible are excellent yellow sweet corn varieties, while those who prefer white varieties can consider Silver King and Silver Princess.

For bi-color corn lovers, Temptation and Delectable are good varieties for freezing. Who knew corn varieties have such fun names?

What Is The Best Corn To Freeze

If you are freezing corn, chances are it’s because you want to enjoy the summer crop later in the year, even if it’s no longer in season. So, how do you pick a corn that will freeze well?

Of course, select fresh corn. These cobs typically have bright green husks tight to the ears of corn.

The husk is not dry, and the cob is covered with plump, firm, and not-too-mature kernels from top to bottom.

Oh! And here’s an additional tip from PennState Extension: It’s best to preserve corn within 6, or much better, 2 hours of harvest, so waste no time and get started on freezing those crops ASAP!

Is it better to freeze corn on the cob or off the cob?

You can freeze either corn on the cob or whole kernels. You can even freeze cream-style corn!

Just note that freezing corn on the cob will take up more space in the freezer. Some people also prefer freezing corn off the cob because uncut corn is prone to having a “cobby” taste. This usually happens if the cobs are not cooled completely after blanching!

Finally, work with small amounts of corn at a time. It’s recommended not to freeze more than 2 pounds per cubic foot of freezer capacity per day.
