Said to date back to pre-Columbian times, atole is a very thick beverage that's popular in Mexico and some parts of the American Southwest. It's a combination of masa, water or milk, crushed fruit and sugar or honey. Latin markets sell instant atole, which can be mixed with milk or water. Atole can be served hot or room temperature.
