On the 4th of November 1492, Columbus came ashore on what is now the island of Cuba. The natives greeted him with a gift of corn. Because it is a strong plant, grows fast and produces food for both people and animals, it has been cultivated everywhere but the North and South Poles. We'll see how corn oil, corn starch and corn syrup have become essential to every industrial society on the planet. We' ll discover the source of corn flakes, and find out how gourmet popcorn was invented.
