Improvise showing ingenuity bottling blended gin (4,2)
I believe the answer is:
wing it
'improvise' is the definition.
(I've seen this before)
'ingenuity bottling blended gin' is the wordplay.
'ingenuity' becomes 'wit' (wit can mean cleverness or ingenuity).
'bottling' is an insertion indicator (bottling is a kind of containing).
'blended' is an anagram indicator.
'gin' with letters rearranged gives 'ing'.
'wit' placed around 'ing' is 'WING IT'.
'showing' is the link.
(Other definitions for wing it that I've seen before include "Perform without any preparation" , "Improvise" .)
