Villagers at Whakarewarewa still cook food in steam boxes and mineral pools fed directly by boiling ground water — no pot ever touches a flame, because the earth itself supplies the heat.
Corn cobs are lowered in flax baskets or muslin cloth into steam boxes and hot mineral pools built directly over natural geothermal vents, where volcanic steam cooks them through in minutes. It's a signature sight and snack at Rotorua's living Māori village of Whakarewarewa, where the same steam is used to cook whole family meals every day.
