| 2 | 6-8 minutes |
| 3 or more | 8-10 minutes |
Step 5: Check for Doneness
After microwaving, carefully remove the dish (it will be hot!) and uncover it slowly to avoid steam burns. Test for doneness by piercing a kernel; it should be tender but still firm. If it seems undercooked, microwave in 30-second increments until done.
Step 6: Ice Bath to Stop Cooking
Once the corn is perfectly cooked, it’s crucial to halt the cooking process by transferring it to an ice water bath. Fill a large bowl with cold water and ice, and submerge the corn for about 5 minutes. This shock treatment not only stops any further cooking but also helps preserve the vibrant color and crisp texture.
