I will have to try the microwave method but HUGE fan of grilled corn on the cob. Many local sweet corn farms near us... I could do a thread but is actually simple just messy. Grill your proteins first and hold. Throw unshucked cobs on a HOT grill and let them rip. Let it smoke, catch fire, char, and burn. The husk will protect it but the smoke will penetrate the corn. 10-15m but you can tell they're done by smell. Shuck with some old towels outside. Wife likes hers really charred and less smoky so I strip more husk off hers. Very old farmer's tale here is that a good crop is "knee high by the 4th of July".
