According to legend a group of thieves during a European plague outbreak were robbing the dead or the sick. When they were caught, they offered to exchange their secret recipe, which had allowed them to commit the robberies without catching the disease, in exchange for leniency. Another version says that the thieves had already been caught before the outbreak and their sentence had been to bury dead plague victims; to survive this punishment, they created the vinegar. The city in which this happened is usually said to be Marseille or Toulouse, and the time period can be given as anywhere between the 14th and 18th century depending on the storyteller.
