Cookstr, a food site that samples recipes from cookbook superstars and celebrity chefs, recently launched in beta. The site hopes to give users a sample of recipes online and entice them to buy the books. Already signed up are chefs from Jamie Oliver (”The Naked Chef”) to Fergus Henderson (Nose to Tail) to Mario Batali (Chez Panisse) to Madhur Jaffrey (famous for Westernized Indian). It’s mostly a Western crowd, but that’s to be expected.
