When you pile too many ears of corn into the microwave, the steam won’t cook them evenly. Always give space for steam to circulate, ideally cooking in batches.
#2: Forgetting the Ice Bath
Failing to cool the corn immediately after microwaving can lead to overcooked kernels. Always prepare an ice bath in advance.
Storing Blanched Corn
Freezing Corn
Blanching is a crucial step if you’re looking to freeze corn. Properly blanched, then cooled corn can last up to 12 months in the freezer without significant loss of quality.
Refrigerating Corn
If you plan to use the corn shortly after blanching, store it in an airtight container in the refrigerator. It should keep fresh for about 3 to 5 days.
Conclusion
Blanching corn in the microwave is an incredibly efficient technique that brings out the best in this beloved summer vegetable. Not only does it help preserve essential nutrients and flavor, but it also makes the cooking process quicker and cleaner. By following the outlined steps and tips, you can enjoy perfectly blanched corn that can be frozen or used immediately. So, the next time you find yourself with an abundance of fresh corn, remember that a microwave is a handy ally in your kitchen arsenal. Happy cooking!
