Father's attempt to get food (6)
I believe the answer is:
pastry
'food' is the definition.
(I know that pastry is a type of baked goods)
'father's attempt' is the wordplay.
'father's' becomes 'pa's' (pa can mean dad or father).
'attempt' becomes 'try' (synonyms).
'pas'+'try'='PASTRY'
'to get' acts as a link.
(Other definitions for pastry that I've seen before include "Sweet baked dough" , "Kind of baked food" , "Choux --; puff --" , "Dough made from flour, fat and water" , "choux, perhaps" .)
