Made it with rice cooked for so long (11)
I believe the answer is:
arrivederci
'so long' is the definition.
(synonyms)
'made it with rice cooked' is the wordplay.
'made it' becomes 'arrived' ('arrive' can be a synonym of 'make it').
'with' says to put letters next to each other.
'cooked' is an anagram indicator.
'rice' with letters rearranged gives 'erci'.
'arrived'+'erci'='ARRIVEDERCI'
'for' is the link.
(Other definitions for arrivederci that I've seen before include "so long abroad" , "Italian farewell" , "Italian goodbye" , "final word" , "Until we meet again (Italian)" .)
