CanSmoke, you'd have to get really aggressive with a heavy and long smoke before it would be strong with husk-on corn...same goes for potatoes. They may smell so strong of smoke that you'd think you won't even be able to eat it, but if you used proper smoking technique (no stale smoke or creosote) it should not smell off-putting (acrid, bitter) and will be good eating. The skin on the corn kernel prevents much of the smoke from penetrating into the corn itself, and the husk and silk slows the accumulation of smoke on the kernels, so you basically have 2 levels of anti-smoke protection built into a whole cob of corn. Now take that same corn and cut it off the ear??? Yeah, better be careful with your smoke then. I can't say that I've ever over-smoked whole ear corn or potatoes...it would be pretty tough to pull off a boo-boo like that.
With whole ear corn (leave whole) and potatoes (we don't the potato skins when smoked) they're actually better if refrigerated for a couple days in a closed plastic bag...fridge will smell of smoke but the goods are even better after having some time for the smoke to penetrate. Like with smoked cheese and a good wine or whiskey, they get better with time. Reheat and enjoy!!!
