Light their dusk - produce confectionery (7,7)
I believe the answer is:
turkish delight
'confectionery' is the definition.
(Turkish Delight is an example)
'light their dusk produce' is the wordplay.
'produce' indicates anagramming the letters.
'light'+'their'+'dusk'='lighttheirdusk'
'lighttheirdusk' with letters rearranged gives 'TURKISH DELIGHT'.
(Other definitions for turkish delight that I've seen before include "Sweet" , "consequence of a future decision on EU admission?" , "pleasure in Ankara" , "Jelly-like confection ..." , "Confectionery" .)
