When it comes to Greek cookbooks, "The Glorious Foods" is the book to beat. The 400-plus recipes are organized by region, from the Aegean islands to the Peloponnese. Kochilas, a Greek-American now residing in Greece, includes much historical and cultural information -- with the result that her book is as wonderful an introduction to the place as it is to the cuisine.  (GRE154, $40.00)
