Fisherman's Stew or Cioppino is a tomato-based seafood stew that was invented by the San Francisco Italian fishermen of North Beach in the late 1800s using whatever seafood was left over from the day’s catch. Often times it was a crab, shrimp, clams, and fish, which were then combined with onions, garlic, and tomatoes, and then everything was cooked with herbs in olive oil and wine. Originally it was made on the boats while out at sea and in homes, but as Italian restaurants started sprouting up around the wharf, cioppino became a very popular dish at local restaurants.
