Light the torches and grab the paper umbrellasthe handbook of delicious tiki beverage is here. In this book, former bartender Adam Rocke selects his favorite tropical libations. The effect of tiki or boat drinks, says the author, is to evoke the sensation of being marooned on a tropical island with a bevy of insignificant others eager to do your bidding. Filling the bill are pina coladas, daiquiris, tropical punches, margaritas, freezes, coolers and other classics that will conjure island breezes and rolling waves. Lesser-known but equally transporting drinks include such creative variations as the Pirate's Cove, Buccaneer, Zombie, Frozen Mudslide and Bahama Mama. In addition to serving up liquid exotica, Rocke offers tips on mixers, glasses and serving techniques.
