House embracing a new flavour (7)
I believe the answer is:
vanilla
'flavour' is the definition.
(I've seen this before)
'house embracing a new' is the wordplay.
'house' becomes 'villa' (villa is a kind of house).
'embracing' is an insertion indicator.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'a'+'n'='an'
'villa' placed around 'an' is 'VANILLA'.
(Other definitions for vanilla that I've seen before include "Flavour got from pods" , "without additions" , "conventional" , "Tasty flavouring for ice-cream" , "Commonplace - flavouring" .)
