When I travel, one item I purchase for my collection is a regional cookbook. My Mom has accompanied me on vacations and loves to review the trip by looking at the cookbook. I generally have to modify cooking recipes but having purchased the cookbook in the area somehow makes the recipe and the book precious.
Friends visiting cities such as New Orleans or Dallas have borrowed my cookbooks when preparing for their trips. I also love the cookbooks purchased in smaller towns, those detailing local events and international books. These cookbooks make cooking fun and bring back wonderful memories of our vacations.
