HOT TAKE: This text is super-comprehensive, both in its citations (MANY to mine) and its coverage of how immigrant cuisine went from being a siloed part of the American food culture to deeply integrated into everyday American life. Gabaccia weaves together extensive historical research with five key case studies of New York, Charleston, San Antonio, San Francisco, and Minneapolis-St. Paul, to show how different immigrant communities have innovated upon and expanded upon the American palate. While her earliest chapters on American colonial appetites are not particularly innovative (James McWilliams does a lot more meaningful work here), her chapters about the expansion of immigrant diets into mainstream American food (including processed food) are especially interesting, as they give credence to the rise of the ethnic entrepreneur as a force within the broader food system, and to the evolution of the American appetite. Even as she notes the occasional nativist backlashes (did she ever remark on Calvin Trillin's provincial take on Szechuan food?), she also notes that by the late 20th century Americans have had foreign flavors so embedded in their diets that they have ceased to be a threat. Moreover, she talks about the fact that ethnic entrepeneurs have not always made foods directly expressive of their own heritages, but have mixed and matched over time, just as Americans have mixed origin stories on their plates. The one critique I have is that there is not very much discussion of African-American foodways throughout the text, and that the text might have benefitted from a different structure that would make her field studies more present/central to her analysis. Nevertheless, a great volume, and in particular Chapters 3, 4 and 6 are especially great.
