Three and a half years after Hurricane Katrina devastated the city, a still-recovering New Orleans may not be up to belting out “laissez les bon temps rouler” – let the good times roll – with all its usual gusto. But this year will surely be tastier, thanks to a new heartfelt and heartwarming book, “Cooking Up a Storm” (Chronicle, $24.95). The book’s subtitle explains it all: “Recipes Lost and Found from The Times-Picayune of New Orleans.” Katrina and the subsequent flooding not only killed many and left billions of dollars in property damage, but the storm washed away countless family recipes, those lovingly hoarded scraps of notepaper and newspaper on which family meals and family memories were made.
