If you have read the same author's "Wings of Cherubs" you will know that he is a detail-focused historian with a singleminded obsession with the history of pisco, the peruvian grape spirit, in pre-prohibition San Francisco.
That might sound a little arcane, but it's important for any lover of historical cocktails: pisco was the drink of choice in San Francisco a century ago, and yet now so little is known about it in the US that even the recipe for Pisco Punch, once a must-drink cocktail for any visitor to the city, has been lost.
It's that kind of mystery that set Toro-Lira on a nearly decadelong hunt through old archives and newspapers and dusty manuscripts to try to discover the lost recipe (his reconstruction is inspired and delicious). That hunt turned into the magical-realist "Wings of Cherubs."
For those interested in the hard facts -- the clippings, the photos, the ships logs, and so on -- they are all collected in this book, "History of Pisco in San Francisco." It was a monumental research effort, and this volume is a gift to the rest of us who haven't the skill or the fortitude to do something like that ourselves. It goes beyond pisco to present a snapshot of SF history, and in particular the surprising Peruvian role in it.
