Dye made from vanilla extract (4)
I believe the answer is:
anil
'dye' is the definition.
(anil is a kind of dye)
'from vanilla extract' is the wordplay.
'from' says the answer is hidden in the clue.
'ANIL' can be found hidden inside 'vanilla extract'.
'made' is the link.
(Other definitions for anil that I've seen before include "It produces dye" , "Shrub providing indigo" , "Colouring" , "West Indian shrub, source of indigo" , "Indigo (plant or dye)" .)
