Heavenly food provided by male relative in vast continent (8)
I believe the answer is:
ambrosia
'heavenly food' is the definition.
(ambrosia is the food of the greek gods)
'male relative in vast continent' is the wordplay.
'male' becomes 'm' (common abbreviation).
'relative' becomes 'bro' (short for brother).
'in' indicates putting letters inside.
'vast continent' becomes 'asia' (I've seen this in another clue).
'm'+'bro'='mbro'
'mbro' inserted into 'asia' is 'AMBROSIA'.
'provided by' is the link.
(Other definitions for ambrosia that I've seen before include "Gods' dinner?" , "dish fit for the gods when cooked without salt" , "good food" , "Food of classical gods" , "Bee bread" .)
