Did you know that George McGovern had a secret salad dressing recipe?

Even his wife Eleanor did not know what was in it. In her cookbook, she described the dressing as having a tangy flavor all its own.

George McGovern was an US senator from South Dakota and the Democratic Party presidential nominee 50 years ago in the 1972 presidential election.

This cookbook is in the Chilson Collection in the Archives and Special Collections at the University of South Dakota.
