Is Anthony Bourdain Writing Another Cookbook?

Yesterday, a photograph was posted on Instagram with a caption suggesting that Anthony Bourdain was writing a(nother) cookbook. New York City-based ice cream heroes and noted best friends of one Mr. Anthony Bourdain and his wife Mrs. Ottavia Bourdain, Douglas Quint and Bryan Petroff — otherwise known as the Big Gay Ice Cream guys — posted the following photograph and caption:

I'm trying to choke down the osso buco recipe that this guy is going to include in the cookbook he is writing but is keeping secret.

Anthony Bourdain has been writing books for decades, but the only cookbook he's written is the one he authored for Les Halles, his one-time employer, back in 2004. Since then, Bourdain has written the forward to the Treme cookbook, and started his own cookbook imprint with Ecco, itself an imprint of HarperCollins. Los Angeles-based chef Roy Choi's first book, L.A. Son, was among the first to be published by Bourdain's imprint in 2013.

Though Publishers Marketplace has not announced the new book, all signs point to a new Bourdain book sometime in the next 12 to 24 months. Could it be a compilation of greatest hits after years of traveling abroad? Or would it be a sort of 'Bourdain at Home' book to sooth his fan base?

Eater reached out to Bourdain's camp for comment, and a rep wrote back: "Nothing to confirm today, except that any future titles from Tony would be published by ECCO, but not the Bourdain books imprint." Eater has also reached out to ECCO and HarperCollins but has not heard back.

One thing we do know: The book will likely include a killer recipe for Osso Bucco.
