Curry was one using fish and rice starter (6)
I believe the answer is:
skater
'curry was one' is the definition.
(John Curry was a figure skater)
'fish and rice starter' is the wordplay.
'fish' becomes 'skate' (skate is a kind of fish).
'and' means one lot of letters go next to another.
'starter' indicates taking the first letters.
The first letter of 'rice' is 'r'.
'skate'+'r'='SKATER'
'using' is the link.
(Other definitions for skater that I've seen before include "One sliding over ice" , "Winter sportsman" , "Winter sportsperson" , "Winter sports participant" , "Rink glider" .)
