Growing up in Ft. Wayne, IN...I've learned that soaking corn will remove the sugar especially if its for longer than 10 minutes.
A simply peel back and clean is all you need, the husks wont absorb much water when soaked.
If you must soak, simply dunk in water to load the husk with a little extra water when grilling.
Grill for about 20 minutes turning several times with the husk on....The water in the husk basically helps to boil or steam the corn.
Remove, lather in butter and sprinkle with salt.
Charred husks on makes a nice presentation.
Boiling corn is very easy, 10-15 minutes tops but, I add sugar to the water to compensate for any sugar being removed in the process.
My favorite way is to fully clean the corn, remove everything and break in half.
Throw on the grill at high heat for a 3 minutes, turning several times...with a little char is ok.
Have some foil ready to go to wrap each piece.
I wrap half of them with some butter and a pinch of salt (for the kids)
The adult half, I brush mayo, sprinkle pepper and just a bit of asiago or parm cheese....maybe even some chili powder, depends on the crowd.
After they are wrapped, I throw them on the top row while I char some flesh!
Just the way I've learned and I have no complaints...Corn is great, easy and fun especially this time of year
