There is ample evidence that we treat these foods as inferior, as Krishnendu Ray, the chair of nutrition and food studies at New York University, writes in his new book "The Ethnic Restaurateur." Ray points to the comparatively low price ceiling for various "ethnic cuisines," as a telling sign. Despite complex ingredients and labor-intensive cooking methods that rival or even eclipse those associated with some of the most celebrated cuisines — think French, Spanish and Italian — we want our Indian food fast, and we want it cheap.
