I have posted recipes from the cookbook, "White Trash Cooking." There are now three volumes, and a couple of auxiliaries, of this longtime favorite, all available from your book dealer. They are excellent antidotes to the uper caste Southern Junior League cookbooks which used to be ubiquitous (maybe still are).
Northerners or foreigners should not use the term because they have no knowledge of its use and evolution (like all such terms, meaning and application change with time and locale). Its old application to the poor employed white has mostly disappeared.

Trailer trash has acquired a different meaning and use since its coinage. Southern natives facetiously apply the term to northerners who come down in cold weather and congregate in trailer parks.
