Doris, to me, nearly all the Mexican food that has been made for
typical American taste buds has the same ingredients, and the way
the dish is assembled and how much of each ingredient is included
determines what it is called. I am probably wrong, but my comment
Is based on my experience here in the Midwest. I think differences
are probably more pronounced nearer the border or in areas where
there are more concentrated Mexican-culture communities.
