Stranger's after fine food (6)
I believe the answer is:
fodder
'food' is the definition.
(fodder is a kind of food)
'stranger's after fine' is the wordplay.
'stranger' becomes 'odder' (I've seen this before).
'after' is a charade indicator (letters next to each other).
'fine' becomes 'f' (abbreviation).
'odder' put after 'f' is 'FODDER'.
(Other definitions for fodder that I've seen before include "Straw to eat" , "Animal feed" , "Bulk feed for livestock" , "Food for livestock" , "Lucerne etc" .)
