Criticise attempt to find food store (6)
I believe the answer is:
pantry
'food store' is the definition.
(cupboard for storing food)
'criticise attempt' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'attempt' becomes 'try' (synonyms).
'pan'+'try'='PANTRY'
'to find' is the link.
(Other definitions for pantry that I've seen before include "Room off the kitchen" , "Small storeroom for food etc" , "Store cupboard" , "Small room or cupboard for storing food" , "Food store" .)
