Here is a link to pics of this almost black corn , and complete anthology :http://herbalguides.com/guides/purple-corn
The silk tussel (male flower) is also edible, they reduce blood sugar levels, gout - they are a source of phenoxyacetic esters, so are mldly stimulant, and vasodilator, how good are Tassels!
Interesting it is native to the Incas, and Southern Mexico and not found wild anywhere in the world.
The purple corn has higher anti-oxidant potency and anti-radical kinetics than blueberries, suffice to get anthrocyanins in corn at all !
And raw is best ! If anyone is interested in a raw marsala hotpot, ( tell me if this is not raw food ) lightly heat coconut cream with marsala powder then drop washed , sliced corn, broccoli, asparagus , bok choy , carrots , ginger , papitas , sesame seeds , marsala , and Sindhi biryani. Do not boil, total time < 3mins ( after preparation ). The vegies just get warm, they don't cook. Finally add sliced medium ripe (semi-green) banana., top with fresh coriander.
