Luxury food coming from America via Russia (6)
I believe the answer is:
caviar
'luxury food' is the definition.
'caviar' can be an answer for 'food' (caviar is a kind of food). I'm not certain of the 'luxury' bit.
'from america via russia' is the wordplay.
'from' indicates a hidden word.
'CAVIAR' is hidden within 'america via russia'.
'coming' acts as a link.
Can you help me to learn more?
(Other definitions for caviar that I've seen before include "Sturgeon eggs" , "... prized delicacy" , "Sturgeon delicacy" , "produce of Russia?" , "Expensive roe" .)
