I feel your pain! Wish I could ship you some of the "good stuff," but by the time it got there, it would be the same a supermarket corn!
I never buy more than enough for a couple of days at a time, as that's about how long you want to hold it. Even then, I'll soak 2nd day corn in salt water for a couple of hours before tossing them on the KK. Will go out and buy some today for dinner tonight, just because I can - bwah, ha, ha!
