Turkish delight is one of the few things I enjoyed about Greece (without the chocolate, it's called loukoumia in Greek)--we went to a monastery where these monks were selling their own hand-made version, rose-flavored, with walnuts. I mistakenly bought the lemon version and cursed myself.

But, yeah, not worth going back to Greece for, and I think Edmund's desire for it is a sad comment on his stupidity and the privations of wartime rationing than anything else.
