Sailor repeatedly getting end of sausage served raw (7)
I believe the answer is:
tartare
'served raw' is the definition.
(term in cuisine meaning served raw)
'sailor repeatedly getting end of sausage' is the wordplay.
'sailor' becomes 'tar' (slang term for a sailor).
'repeatedly' says to double the letters.
'getting' means one lot of letters go next to another.
'end of' indicates one should take the final letters.
The final letter of 'sausage' is 'e'.
'tar' duplicated is 'tartar'.
'tartar'+'e'='TARTARE'
(Other definitions for tartare that I've seen before include "Mayonnaise-based sauce with capers, eaten with fish" , "9, 7" , "(Mayonnaise) sauce; raw (steak)" , "(Of fish or beef) served chopped and raw in small cakes" , "Type of mayonnaise sauce" .)
