Why Was Turkish Delight mentioned in Narnia?

The bleak and depressing times of the Second World War was hardly the time for pounds of exotic sweets. But, yet in the book, The Lion, the Witch, and the Wardrobe, Turkish delight, features prominently.

Herein Edmund Pevensie enters an ordinary bedroom wardrobe and discovers a magical snowy kingdom. Here he also encounters a mysterious, yet suspicious Queen, who bribes Edmund with his favourite Turkish delight, in return for betraying his siblings.
