The most important moment for popcorn was definitely the seventeenth century. During this period, in fact, a Spanish missionary, Bernabé Cobo, wrote about how the indigenous people toasted a certain type of corn up to make it explode: "they call it pisancalla and they use it as a sort of pastry". Starting from this period, the culture of corn was immediately and exponentially spread, substituting some other "poor" cereals such as the millet. In some areas of Italy, corn became practically the only food consumed.
A curious fact is that, in the 1920s, with the origin of the cinema, the idea of consuming any food with high levels of noise pollution, such as popcorn, was completely inconceivable in luxurious cinemas, since in these environments the "crunch" was not appreciated.
