I've had some grilled white corn in some parts in south Mexico, prepared in different ways, they're all pretty good and non are sweet, I've been looking to grow some but most of the seeds I find say sweet corn, anyone know what kind they are? some searching led me to hickory king, is that a good candidate or what other options are there (that are not the result of human tampering :)
Some white non-supersweet corn varieties I know of that regularly get high marks for flavor when picked in the milk stage are Stowell's Evergreen and Country Gentleman. I've grown these at one time or another and thought they were very tasty (I also don't like the new super sweet varieties - they just don't taste like corn to me...) These varieties are also open pollinated, meaning you can save seed from them for next year if you only grow one variety or if you isolate the plants in some fashion (look up seed saving, corn, for details - I think Seedsavers.org has a good set of tutorials.) Silver Queen is an older hybrid type that is sweeter than many older open pollinated types, but not nearly as sweet as the new super sweet sugary hybrids, so you might try that one as well, even though the seed won't save true.
