Food from Portugal I mentioned (7)
I believe the answer is:
aliment
'food' is the definition.
(I know that aliment is a type of food)
'from portugal i mentioned' is the wordplay.
'from' indicates the answer is hidden within the clue.
'ALIMENT' is hidden in the letters of 'portugal i mentioned'.
(Other definitions for aliment that I've seen before include "Nourishment" , "Sustenance" , "Old word for food" , "Something which nourishes - meal tin (anag)" .)
