What is a ‘Companion’ for?
It is a brave man who would take on the job of writing a history of Germany and the Holy Roman Empire between 1493 and 1806. Many historians would maintain that neither Germany nor even German national consciousness (certainly not German nationalism) existed during this period; as for the Holy Roman Empire, there is a long-running dispute over what it actually amounted to.
The Ottoman Empire, over the course of its existence, evolved a cultural synthesis of strands coming from its Arab, Persian and Byzantine antecedents, as well as the folk culture of its constituent populations. Culinary traditions were part of this legacy, and the taste for sweets an ever popular and refined element, constituting a repertoire extending into modern Turkey and the Middle East.
At first sight this looks like another of those increasingly common commodity books, some of which are intended to be global in scope, and which include studies of chocolate, sugar, cod, salt and many others (digestible or not!). As Riello points out, commodities are a good way to tell a global story since many of them have been traded throughout the world for centuries.
