Nut found in salmon dish (6)
I believe the answer is:
almond
'nut' is the definition.
(I know that almond is a type of edible nut)
'in salmon dish' is the wordplay.
'in' indicates a hidden word.
'ALMOND' is hidden in the letters of 'salmon dish'.
'found' is the link.
(Other definitions for almond that I've seen before include "Edible nut" , "Type of nut" , "Marzipan-producing nut" , "Nut which provides cake icing" , "Old man (anag)" .)
