Philadelphia cuisine

The cuisine of Philadelphia was shaped largely by the city's mixture of ethnicities, available foodstuffs and history. Certain foods have become iconic to the city. Invented in Philadelphia in the 1930s, the cheesesteak is the most well known icon of the city, and soft pretzels have become a part of Philadelphia culture. The late 19th century saw the creation of two Philadelphia landmarks, the Reading Terminal Market and Italian Market. After a dismal restaurant scene during the post-war era of the 20th century, the 1970s brought a restaurant renaissance that has continued into the 21st century.

Many foods and drinks associated with Philadelphia can also commonly be linked with the Pennsylvania Dutch.

Philadelphia's large immigrant population has contributed to a large mixture of tastes to mingle and develop. Many types of foods have been created in or near Philadelphia or have strong associations with the city. In the 20th century, Philadelphia's most iconic foods were established as the cheesesteak, hoagie, soft pretzel, water ice and soda.

The cheesesteak is a sandwich traditionally made with sliced beef and melted cheese on an Italian roll. In the 1930s, the phenomenon as a steak sandwich began when hot dog vendor brothers Pat Olivieri and Harry Olivieri put grilled beef on a hot dog bun and gave it to a taxi driver. Later, after Pat and Harry had started selling the sandwich on Italian rolls, the cheesesteak was affixed in the local culture when one of their cooks put melted cheese on the sandwich. Originally, the cheese was melted in a separate container to accommodate their large clientele who followed kosher rules (thereby not mixing dairy and meat). Today, cheese choices in Philadelphia eateries are virtually limited to American, Provolone, or Cheez Whiz. The latter is especially popular in those places that prominently carry it.
