In December 2010, Harper released a cookbook titled The Crabby Cook Cookbook: Recipes and Rants. In a January 2011 interview Harper said, "I thought it was high time there was a book that acknowledged that not everybody experiences the joy of cooking, that sometimes cooking for a family on a daily basis can be really irritating! This book, with 135 easy recipes, is for those people, crabby cooks like me! It's a collection of humor, survival tips and recipes, for the kitchen-challenged!" In March 2011, she was on tour promoting her book. Stops included Chicago, where she held a "Lunch and Learn with Jessica Harper".
