Cioppino was developed in the late 1800s by Italian immigrants who fished off Meiggs Wharf and lived in the North Beach neighborhood of San Francisco, many from the port city of Genoa. When a fisherman came back empty handed, they would walk around with a pot to the other fishermen asking them to chip in whatever they could. What ever ended up in the pot became their Cioppino. The fishermen that chipped in expected the same treatment if they came back empty handed in the future. It later became a staple as Italian restaurants proliferated in San Francisco.
