Be sure to season your water with a little salt, especially if this is the only method you will be using to cook the corn.
Remove a kernel or two from the water with the spoon after 2 to 4 minutes to check that the corn is tender.
You may need to run the frozen corn, while still in the bag, under warm water to reduce clumping.
Check to see if your steamer has enough water left, no less than 1 inch, before steaming your corn.
This is a good point to add more seasoning, like salt and pepper. In addition to eating it as is, corn sauteed in butter can be used for making succotash and a variety of other dishes.
The overall microwave time of corn should be around 2-3 minutes on a high setting.
