This is a surprisingly interesting and enjoyable book. While the focus is, of course, on Marshmallow Fluff, Graney explores the history of various forces and events that lead to Fluff's creation and have effected it over it's 100 year history. There's a nice discussion of Boston's history as a candy-making center, which I didn't know about, plus a mention of the Great Molasses Flood, one of my favorite bits of local history. There are histories of radio programs, the expansion of grocery stores into national supermarket chains, the effects both World Wars had on Fluff, and much more. Graney's thesis is that Fluff is a microcosm of America in the last hundred years, and certainly it is fascinating to see how the plucky marshmallow brand spread from my hometown to the whole world. A late chapter mentions how Fluff is branded differently in Japan, with an emphasis on all the things you can do with it, rather than just the Fluffernutter sandwich. And speaking of that childhood classic, apparently the makers of Fluff hold the trademark on the name. There's a lot of fun trivia here and a number of photographs and reproductions of advertising materials. Plus, there's a handful of recipes spread throughout. Overall, it's a surprisingly fun and informative little book, and I've gained a new appreciation for something that to me has been a weird little detail of New England life before now. I'm not sure how interesting this will be for people outside of New England, but certainly it's an excellent book for any New Englanders curious about the history of one of our lesser known signature foods, and I'm glad my local library has a number of copies.
