Emcee securing sparkling wine and aromatic resin (6)
I believe the answer is:
mastic
'aromatic resin' is the definition.
(I've seen this before)
'emcee securing sparkling wine' is the wordplay.
'emcee' becomes 'mc' (I am not sure about this - if you are sure you should believe this answer much more).
'securing' means one lot of letters goes inside another.
'sparkling wine' becomes 'asti' (Asti is a type of sparkling wine).
'mc' placed around 'asti' is 'MASTIC'.
'and' is the link.
Can you help me to learn more?
(Other definitions for mastic that I've seen before include "Aromatic resin used to make varnish" , "Substance applied to joints" , "Waterproof sealant" , "Resin used in varnishes" , "Putty-like cement used as adhesive or filler" .)
