In ancient Japan, kitchens were an essential part of daily life. They used a built-in hot dog roller to cook their sausages. The Japanese cuisine is known for its precision and attention to detail, and sausages were no exception. The hot dog roller in their kitchens was made of bamboo or metal and had a rotating mechanism. The sausages were skewered onto the roller and placed over a fire or hot coals. As the roller turned, the sausages cooked evenly, resulting in tender and flavorful sausages. The ancient Japanese enjoyed a variety of sausages, made from different meats such as pork, chicken, and seafood, and seasoned with soy sauce, mirin, and ginger. The hot dog roller was a practical tool in their kitchens, ensuring that their sausages were always cooked to perfection.
