Often described as a nourishing, hearty stew, and one of San Francisco's greatest contributions to culinary history, cioppino is a fish stew that is traditionally made from the catch of the day, combined with tomatoes and wine sauce. Cioppino is often made with crabs, clams, shrimp, scallops, squid, and mussels, while the typical accompaniment might include a local favorite - toasted sourdough bread.

According to a food historian named Jean Anderson, this Italian-sounding dish was invented by the fishermen from Genoa who immigrated to the US and settled in California's Bay Area. It is most likely that cioppino originated on the fishing boats, when the fishermen made use of what was readily available to make their dinner, similar to the French bouillabaisse.

As for its name, some believe it stems from ciuppin, a Ligurian word meaning to chop or chopped, referring to chopping up of the various leftovers of the day's catch.
