Sweet girl this duke upset has photo taken regularly (7,7)
I believe the answer is:
turkish delight
'sweet' is the definition.
(Turkish Delight is an example)
'girl this duke upset has photo taken regularly' is the wordplay.
'upset' is an anagram indicator.
'has' is a charade indicator (letters next to each other).
'taken regularly' indicates alternate letters (letters removed at regular intervals).
The alternating letters of 'photo' are 'ht'.
'girl'+'this'+'duke'='girlthisduke'
'girlthisduke' is an anagram of 'turkishdelig'.
'turkishdelig'+'ht'='TURKISH DELIGHT'
(Other definitions for turkish delight that I've seen before include "pleasure in Ankara" , "Confectionery" , "Jelly-like confection ..." , "consequence of a future decision on EU admission?" , "Sweet" .)
