Ms Jaramillo's book was originally published in 1939 and the recipes are
primarily from Northern New Mexico. Since the cooking differs between
ABQ and Northern New Mexico today, one can imagine it differed even more
in the past.
She doesn't mention burritos at all, but does give a recipe for the
typical flat New Mexico enchilada, using chicharrones.
