Half of standard French milk that’s recalled (7)
I believe the answer is:
partial
'half' is the definition.
(thesaurus)
'standard french milk that's recalled' is the wordplay.
'standard' becomes 'par' (standard of play in golf).
'french milk' becomes 'lait' (I've seen this in another clue).
'that's recalled' says the letters should be written backwards.
'lait' backwards is 'tial'.
'par'+'tial'='PARTIAL'
'of' acts as a link.
(Other definitions for partial that I've seen before include "Keen" , "Fragmentary" , "One-sided" , "Prejudiced - incomplete" , "Showing favouritism" .)
