Country recipe with a so-called fish (6)

Ross

I believe the answer is:

rwanda

'country' is the definition.
(I know that Rwanda is a country)

'recipe with a so-called fish' is the wordplay.
'recipe' becomes 'r' (abbreviation in medical prescriptions).
'with' is a charade indicator (letters next to each other).
'a so-called fish' becomes 'Wanda' (as in the film A Fish Called Wanda).
'r'+'wanda'='RWANDA'

(Other definitions for rwanda that I've seen before include "Hutu and Tutsi country" , "Republic in central Africa" , "Kigali's country" , "Central African country" , "Language" .)

I've seen this clue in The Guardian.
