all i know is that sweetcorn is a strain of maize corn which is high in sugar & it is a recessive mutation of maize/regular corn
regular corn is picked when it is mature while sweetcorn is picked immature to ripen & allow the sugar to turn to starch....sweetcorn is same as regular but slighty more sugary
& i love sugar mmmmmmmmmmmmmm lol
if you dont catch any fish dont worry you can always have a sweetcorn sandwich ( which i have had quiet a few times now )
