Good to know I have been doing this right all along:

So, What’s The Best Way to Cook Corn?

After testing all of these methods for cooking corn on the cob, grilling them in their husks was the clear winner. The husks helped steam the corn, keeping it moist and preventing it from drying out. Also, the husks charred, giving the corn all the bold, smoky flavor of grilling without the drying or burned bits.

If you don’t have a grill, boiling corn in salted water is a great alternative. You won’t get that charred flavor, but the kernels will be plump, juicy, and perfectly salted.
