Cookbook cataloger Jessica’s Biscuit/ecookbooks.com and “Fine Cooking” magazine have formed a strategic partnership. Jessica’s Biscuit will receive full-page advertisement in certain issues of “Fine Cooking”; in exchange, the magazine will receive free promotional messages in e-mail newsletters that the Newton, MA-based cataloger sends to subscribers. “Fine Cooking” promotions will also be placed in outgoing Jessica’s Biscuit orders.
