Hot spring steamed cuisine
On the Shimabara Peninsula, a hot spring resort area, there is a “onsen steamed food” that takes advantage of the hottest spring temperature in Japan. This is a popular local method of using hot spring steam to cook local vegetables and seafood in a healthy way. The “steaming kettles” in the Obama hot spring resort use hot spring water that rises to about 105°C (221°F). The food is placed in a steamer basket and placed in the kettle, where it waits for a while to be steamed until it is hot and ready. There are many restaurants specializing in steamed food in the area, and visitors can enjoy a variety of steamed dishes.
