Chipa guasu is a variety of chipa, a cake based on corn grains with the addition of onions, water, eggs, cinnamon, milk, and cheese. Its name stems from two words - chipa, referring to a variety of corn-based cakes, and guasu, which means big in Guarani, so one can say that chipa guasu is the largest of all chipas.
It is a favorite side dish in Paraguay during the corn harvest, when cooks brown them in hornos, traditional mud adobe-built outdoor ovens. The dish was invented during the Paraguayan War in the mid-1850s, when food was scarce, and people needed food that was affordable, simple, and highly caloric, providing nourishment during the day.
