Why is giardiniera a Chicago thing?

Giardiniera, a popular condiment in Chicago, originated from an Italian pickling tradition that involves preserving a mix of vegetables in a vinegar brine. This method was brought to Chicago in the mid-to-late 19th century by Italian immigrants, particularly those from Sicily. Unlike other regions in Italy, where the brine consists solely of vinegar, the Sicilian version includes oil, a unique twist that significantly influenced the creation of what is now known as Chicago-style giardiniera.

Jeff Johnson, president of V. Formusa Co., Inc., the parent company of Marconi giardiniera, sheds light on the local history: "My great-grandfather Vincent Formusa began packing and selling gourmet pickled vegetables this way in the early 20th century, making it a staple in Chicago as early as then."

Understanding the historical roots of giardiniera not only enriches the appreciation of this beloved Chicago condiment but also highlights the cultural contributions of Italian immigrants to the city’s culinary landscape.
