Step 4: Ice Water Shock
- Prepare Ice Water Bath: While the corn is microwaving, fill a large bowl with ice and cold water.
- Transfer Corn: Once your corn is finished cooking, immediately transfer it to the ice water. This stops the cooking process and ensures the texture remains crisp.
- Soak for a Few Minutes: Allow the corn to sit in the ice bath for several minutes before removing it.
Storing Blanched Corn
Proper storage is crucial to keeping your blanched corn fresh:
Refrigerating
- Whole ears can be stored in the refrigerator for up to 3 days. Ideally, wrap them in a damp paper towel and place them in a sealed bag.
Freezing
- If you plan to freeze the corn, ensure it’s thoroughly dried post-blanching. Place the kernels (or whole ears) in airtight freezer bags, squeezing out any excess air to prevent freezer burn.
- Use within 6-12 months for the best flavor.
Additional Tips for Microwave Blanching Corn
To ensure you achieve top-notch results every time you blanch corn on the cob:
Optimize Cooking Times
The size of the corn and your microwave wattage can affect how long you should cook it. Start on the lower end and adjust based on the texture you desire.
