Country closed your pizzaria, referencing unusually smelly toppings (6)
I believe the answer is:
cyprus
'country' is the definition.
(Cyprus is an example)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for cyprus that I've seen before include "Island member of the European Union" , "Partitioned Med. island" , "Island - legendary home of Aphrodite" , "Mediterranean island country" , "Othello island" .)
