Cyprus has involved the UN, creating a pickle (7)
I believe the answer is:
chutney
'a pickle' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe there's an association between them I don't understand?
'cyprus has involved the un' is the wordplay.
'cyprus' becomes 'cy' (abbreviation).
'has' indicates putting letters inside.
'involved' indicates anagramming the letters (involved can mean confusing or complex).
'the'+'un'='theun'
'theun' with letters rearranged gives 'hutne'.
'cy' placed around 'hutne' is 'CHUTNEY'.
'creating' is the link.
Can you help me to learn more?
(Other definitions for chutney that I've seen before include "Spicy preserve" , "Spiced Indian condiment" , "Spice in it" , "Spicy Indian condiment" , "Relish" .)
