Dried corn has never struck me as something that's refreshing on a hot day. But, unexpectedly, I found myself facing a recipe for just that. Chicha Morada, is a curious drink from Peru, brewed with dried purple corn, fruit, and spices. It's the most simple thing ever - take purple corn (the recipe on my package just said "half a bag") and boil one hour with three liters of water. Then add an apple, pineapple husks, lime juice, cloves, and cinnamon. Boil for 10 more minutes. Sweeten, garnish with more pineapple or apple, and chill. It's crisp and refreshing from the acid of the fruit and citrus, but not at all starchy or heavy.
purple corn meal, while visiting my parents in Arizona. I originally bought this bag of purple corn to see how it would work in stewing with yucca and pork, but the recipe for Chicha Morada printed on the side was something of a distraction. After boiling the corn for an hour, I chopped some of the purple kernels open. They were totally dry. It seemed like the water had just leached the coloring from the surface of the grain. But it made sense - you need to soak cracked dried corn for 4 hours or more, so I imagine whole kernels would require a full overnight soak, like beans.
One site ties a rise in the drink's popularity from recent findings on purple corn's health attributes. But this is also the only site that refers to Chicha Morada as an alcoholic drink, something that contradicts every other reference to Chicha Morada I've found. In looking up purple corn's health benefits, I came across a company that is trying to market a proprietary purple corn hybrid here in the U.S. So mostly noise, no real facts.
Like an itch between your shoulders, I just couldn't let this idea go. Why boil corn for an hour, when all it would do would dye the water? It hadn't penetrated past the outer layer of the corn, so I imagine most of the nutrients and calories wouldn't be extracted. Was it just a use for old, dried-up corn that had sat over the winter and was no longer viable as seed? Of all the corn-based drinks that were fermented, why was this purple drink never fermented (supposedly)?
A half-answer came I found that most Incan history (overlapping modern day Peru) was an oral history, and never recorded before the Columbian era. So maybe why this purple corn drink was created is lost to the ages. All I know is that I lost the better part of an afternoon in researching what turned out to be a snipe hunt. But I did have some nice refreshments along the way,
