The shrimp cocktail was invented in a bar on Boston Harbor in 1941. It was first prepared as a drunken “let’s put gross shit together in a glass and dare people to drink it” concoction with shrimp, ketchup, and vodka. In the end it turned out to be delicious. The kicker, it was served in a cocktail glass, hence the name! Have a Mad Men Moment and serve your next shrimp cocktail in a vintage cup.
