For Years, Dana Cowin kept a big secret. The editor-in-chief of the prestigious Food & Wine magazine could barely cook. With the help of friends who also happened to be all-star chefs, Cowin mastered her meals and she recently shared her kitchen mishaps and how she overcame them in her book, Mastering My Mistakes in the Kitchen: Learning to Cook with 65 Great Chefs and Over 100 Delicious Recipes. Cowin appears at the popular Bottega Restaurant in Napa Valley, presented by Book Passage, for a revealing dinner and reading event. Head chef and television personality Michael Chiarello welcomes the author, as Cowin shares some sure-fire recipes and joins patrons for a sumptuous dinner on Wednesday, Oct. 22, at Bottega Restaurant, 6525 Washington St., Yountville. 6:30pm. $140. 415.927.0960.
