Chicha morada is an unusual drink made from purple corn. The name can be confusing, because the word "chicha" usually refers to fermented beverages that are quite alcoholic. Chicha morada is non-alcoholic, and is made by boiling purple corn with fruit (quince & pineapple), cinnamon and cloves. It tastes both sharp and fruity - similar to mulled apple cider, but spicier and more interesting.
Chicha morada is often served at kid's birthday parties, which is unfortunate really, because it seriously stains clothes. It's a popular afternoon pick-me-up, best enjoyed with an alfajor cookie or an empanada.
You can buy bottled chicha morada at Latin food markets, or try making it at home with this recipe from the Peruvian cooking website Yanuq.
