He stuck a knife into the belly to see if the roast was edible, and out popped the intestines: empty because of the starvation diet, and puffed from the heat. According to legend, Gaius exclaimed, “I have discovered something of great importance!” He stuffed the intestines with ground game meats mixed with spices and wheat.
While the story of Nero's cook has endured for centuries, sausages almost certainly predate the Roman Empire. Archaeological and literary evidence suggests that people were stuffing seasoned meat into animal intestines thousands of years earlier as a practical way to preserve food and make use of every part of a slaughtered animal. An Akkadian cuneiform tablet from Mesopotamia dating back roughly 4,000 years describes intestine casings filled with a meat mixture, making it one of the earliest known references to sausage. Ancient Chinese records also describe an early sausage made from goat and lamb, while Homer's Odyssey, written around the eighth century B.C., mentions blood-filled sausage roasting over a fire.
The sausage traveled across Europe, making its way eventually to present-day Germany. The Germans adopted the sausage as their own, creating scores of different versions to be enjoyed with beer and kraut. In fact, two German towns vie to be the original birthplace of the modern hot dog. Frankfurt claims the frankfurter was invented there over 500 years ago, in 1484, eight years before Columbus set sail for America. But the people of Vienna (Wien, in German) say they are the true originators of the “wienerwurst.”
No matter which town might have originated this particular sausage, it’s generally agreed that German immigrants in New York were the first to sell wieners, from a pushcart, in the 1860s.
