As seen at Bar La Estacion across the street from Arena Mexico (the lucha libre venue):
You’ll see a few common Mexican snacks listed (in varying degrees of spelling accuracy) in the white lettering. But peruse on down to that 4th line of white text. Pene en su jugo. For any non-Spanish speakers, that means pene in its own juice. (Once you click on the word reference definition, you’ll see why I’m eschewing the specific translation in hopes of avoiding further weird Google searches arriving at this blog.)
La Estacion was not serving any food the Friday evening we stopped in prior to the lucha match, so I did not have the opportunity to sample this gem.
Can any Mexicans tell me– is this a popular dish? A common dish, even? Perhaps some jokester removed some letters before pene, though I can’t think what they would have been? Your insights are welcomed.
