I love learning about different dialects and I own all sorts of regional and time-period slang dictionaries. I often browse through relevant ones while writing a story. I also read a lot of diaries and oral histories.

To that class we may leave it to refine the vernacular dialects of the country to enrich those dialects with terms of science borrowed from the Western nomenclature and to render them by degrees fit vehicles for conveying knowledge to the great mass of the population.

Mexican food is far more varied than people think. It changes like dialects. I was brought up in Jalisco by the sea on a basic diet - tomatoes chillis peppers of every size and rice which is a Mexican staple. The Pacific coast has a huge array of seafood.
