Pasties are very available in Mexico. They even have the same name. They came to Mexico with Cornish miners, after Mexico became independent from Spain in the early nineteenth century, to the city of Pachuca, still an important mining town.
There are all sorts of pasties, from traditional to hit chile to sweet ones, an incredible variety.
Pachuca also started football in Mexico as well, and you can blame the miners for that as well !
