Thought it was newsworthy that several versions of Culinaria are (almost unthinkably) now available at bargain prices. If you're not familiar with the Culinaria series, they are spectacular books that focus in most cases on one country, and then relate almost everything there is to know about that country, from the standpoint of food -- products, crops, specialties, beverages, traditions, culture, farming, history, and, of course, recipes. There are also hundreds of photographs. I already had most of them, but just picked up European Specialties (the only one not limited to a single country) and Russia at Borders -- on the bargain racks. They also had Greece, Italy, Germany, and Spain, but I already had those. Since these were originally $60 for the hardbound and $30 for softbound, getting them for $19.99 and $9.99 respectively was pretty exciting.
I've seen a few others from this series at Half Price Books, but they weren't as cheap as the ones at Borders -- though they did have a few other countries.
So if you need to fill out your foodie-lit collection a bit, these are wonderful options. They'd be as good for trvel as for cooking, as they go region by region, identifying the best things to eat and where to get them. Really delightful fun. And gorgeous to look at, as well.
