Flavouring much used in Munich, possibly (5)
I believe the answer is:
cumin
'flavouring' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'much used in munich possibly' is the wordplay.
'much' becomes 'cum' (I am not sure about this - if you are sure you should believe this answer much more).
'used in' means to look at the middle letters (the letters used on the inside of the word).
'possibly' is an anagram indicator.
The central letters of 'munich' are 'ni'.
'ni' with letters rearranged gives 'in'.
'cum'+'in'='CUMIN'
Can you help me to learn more?
(Other definitions for cumin that I've seen before include "Spice used in curries" , "relief from wind" , "Aromatic seeds used in cooking" , "Curry powder ingredient" , "Culinary spice" .)
