People who lived in the Iroquois nation in the northeast part of North America ate mainly corn and beans and squash that they farmed. They made the corn into flat bread like tacos or tortillas. That was the same way that Pueblo and Mexican people ate their corn.
But Iroquois people also cooked corn into polenta (grits) by boiling it in water like oatmeal. They kept a pot of corn mash soup simmering over the fire all day. That’s because it was much colder up north where the Iroquois lived. It was often cold enough to keep a fire going all day long anyway, for heat. People could just dip some corn mush out whenever they got hungry. Iroquois people didn’t generally have set meal times.
