Pink concoction basically taken through the mouth (5)
I believe the answer is:
coral
'pink' is the definition.
(coral is a shade of pink)
'concoction basically taken through the mouth' is the wordplay.
'basically' says to take the initial letters (the first letter could be its root or base).
'taken' says to put letters next to each other.
'through the mouth' becomes 'oral' (I've seen this before).
The initial letter of 'concoction' is 'c'.
'c'+'oral'='CORAL'
(Other definitions for coral that I've seen before include "certain islands" , "Marine growth" , "Pink - lobster roe" , "Main resident" , "rock, perhaps" .)
