That is a fun article with one minor error, and 2 glaring omissions. The minor error is attributing cayenne pepper to Africa. All chile pepper species are endemic to the Americas, though now popular throughout the world, especially in tropical countries.
2 glaring omissions in the article are the Italian
calzone, and the Central American
pupusa, though the latter can be a bit messy to eat with the hands. The food in Central America is mostly pretty dull compared to Mexican cooking, but the pupusa is a sublime invention! Where I live, the Central American immigrant population is large, so it's easy for me to get my
pupusa fix.
