In which US city was the Ragu brand of Italian-style sauces first produced?

Ragu is a brand of Italian-style sauces and condiments owned by in North America by Mizkan, and in the United Kingdom and Ireland by Symington's, a private label food manufacturer. Ragu had its beginnings in Rochester, New York in 1937. Assunta Cantisano and her husband Giovanni founded the Ragu Packing Company in their home in Rochester, New York in 1937, making spaghetti sauce in their basement and selling it on their front porch. They later expanded to an entire factory. In 1969, the Ragu name was sold to Chesebrough-Pond's. The facility in Rochester still manufactured products under the Cantisano name brand. Some of the original facility still exists and produces products for other labels (including Newman's Own) as private label foods.

In its first several decades, Ragu advertising and sales broadened the appeal of Italian-American food in the United States, with slogans like "That's Italian!" and "Ragu brings the Italian out in you!" Americanized Italian cuisine is now the most common "ethnic" cuisine served in U.S. households, followed by variations of Americanized Mexican cuisine. Current advertising highlights the natural ingredients and "full serving of veggies" found in the sauce. Cooked tomato foods, including Ragu, are highlighted as containing the antioxidant lycopene, which is claimed to be a cancer fighting agent. As of 2015, the advertising campaign refers to the creation of Ragu with the phrase "Simmered in Tradition."
