Food company finally fixed trough (7)
I believe the answer is:
yoghurt
'food' is the definition.
(yoghurt is a kind of food)
'company finally fixed trough' is the wordplay.
'finally' says to take the final letters.
'fixed' indicates anagramming the letters.
The final letter of 'company' is 'y'.
'trough' with letters rearranged gives 'oghurt'.
'y'+'oghurt'='YOGHURT'
(Other definitions for yoghurt that I've seen before include "Bacteria-treated milk product" , "Healthy food" , "culture" , "Health food" , "Semi-liquid food" .)
