In ancient Viking culture, kitchens were an important part of daily life. They used a built-in hot dog roller to cook their sausages. The Vikings had a hearty and meat-centric cuisine, and sausages were a staple. The hot dog roller in their kitchens was made of metal and had a rotating mechanism. The sausages were skewered onto the roller and placed over an open fire. As the roller turned, the sausages cooked evenly, resulting in delicious and smoky sausages. The ancient Vikings enjoyed a variety of sausages, made from different meats such as pork, beef, and fish, and seasoned with herbs like dill, thyme, and juniper berries. The hot dog roller was a practical tool in their kitchens, ensuring that their sausages were always cooked to perfection.
