@Doctor_Malsyn Some old British cook book published decades earlier than the legend is the first verified source. However, chances are it's still older, but why would anyone record something like that for historians to study?

@Kaarme What are their actual origin then?

@Kaarme I actually never knew that the story was made up. Cool fact.

Nothing but an artificial legend used in marketing. Kind of like Apple would have you believe they invented the touchscreen smartphone.
