Fresh aroma around most of Vietnamese soup in jar (7)
I believe the answer is:
amphora
'jar' is the definition.
(amphora is a kind of jar)
'fresh aroma around most of vietnamese soup' is the wordplay.
'fresh' is an anagram indicator.
'around' means one lot of letters goes inside another.
'most of vietnamese soup' becomes 'ph' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'aroma' with letters rearranged gives 'amora'.
'amora' enclosing 'ph' is 'AMPHORA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for amphora that I've seen before include "Classical jar for storing liquids" , "Ancient Greek storage jar" , "wine-holder" , "Ancient jar with two handles, for wine" , "Ancient Greek two-handled jar" .)
