Tips and tricks for freezing corn (on or off the cob)
When it comes to preserving the deliciousness of fresh corn, freezing is your best bet. Whether you prefer corn on the cob or just the kernels, freezing allows you to enjoy this summer staple all year long. Here's a comprehensive guide by SSP on how to freeze corn, containing valuable tips and techniques to ensure the best results.
First things first, let's talk about selecting the perfect corn for freezing. For optimal quality, it is recommended to purchase corn from a farmer's market or local stand rather than a grocery store. Look for signs of freshness such as vibrant green husks tightly wrapped around the cob. Avoid any corn that appears dry, cracked, or has a yellow/brown color. Check for golden and sticky silk tassels at the top of the corn, ensuring they are not black or dry as it indicates the corn's age. Choose corn that feels heavy and firm in your hand, with plump kernels distributed evenly. Be sure to steer clear of cobs with wormholes or signs of bug infestation.
Freezing corn on the cob (whole):
Step 1: Shuck the corn. Rather than peeling the husk leaf by leaf, here's a simple hack. Start by cutting off about ½ inch from the root end of each corn cob using a sharp knife. With a firm grip on the top of the cob (where the tassels are) and holding the bottom of the cob with your other hand, twist and pull to easily free the corn from the husk.
Step 2: Blanch the corn. While it is possible to freeze corn on the cob without blanching, it may result in a slightly watery and chewy texture after cooking. To ensure the best quality, blanching is recommended. Boil a large pot of water and carefully submerge the corn, ensuring it is fully covered (heat-proof tongs can be handy for this). Boil for exactly 4 minutes with the lid on. In parallel, prepare an ice bath by filling a container with water and plenty of ice.
Step 3: Cool and dry. After the 4 minutes are up, use the tongs to remove the corn from the boiling water and immediately transfer it to the ice bath. This rapidly cools down the corn and stops the cooking process. Let the corn sit in the ice water for about 10 minutes. Once cooled, thoroughly dry the corn using kitchen or paper towels.
Step 4: Freeze. Arrange the blanched dried cobs on a freezer-safe tray and place them in the freezer until they become solid (this usually takes a few hours or overnight). Afterward, transfer the cobs to a Ziplock freezer bag or wrap them tightly individually. Don't forget to label the bag or wrap it with the current date for easier organization. Store the corn in the freezer.
Freezing corn off the cob (corn kernels):
Step 1: Remove the husk and blanch. Begin by removing the husk from the corn and then follow the same blanching and cooling instructions mentioned earlier.
Step 2: Remove the kernels. To easily remove the kernels, using a Bundt pan is a handy trick. If a Bundt pan is not available, you can try using an inverted small container or bowl placed inside a larger bowl. Stand the corn upright in the hole of the Bundt pan or small container. With a small, sharp knife, slice downward, allowing the kernels to drop into the pan, minimizing any mess.
Step 3: Freeze. Spread the kernels in a single layer on a baking sheet and place it in the freezer until the kernels become solid (usually several hours). Then, transfer them to a Ziplock bag, removing as much excess air as possible before sealing. Don't forget to label the bag with the date before putting it back into the freezer for storage.
It's important to note that properly stored blanched frozen corn, whether whole or just the kernels, can last up to 8-12 months in the freezer, ideally maintained at 0°F/-18°C. If your freezer temperature is higher, make sure to consume the corn within the first 6 months for optimal taste and texture.
With these handy freezing tips, you can keep the taste of fresh corn alive all year round. Enjoy the convenience of having corn readily available for soups, salads, and countless other recipes. Embrace the summer flavors, even when the sunshine fades away!
