Fashionable drug reportedly made from such sauce (6)
I believe the answer is:
coulis
'sauce' is the definition.
(type of sauce)
'fashionable drug reportedly made from' is the wordplay.
I cannot really see how this works, but
'fashionable' could be 'u' and 'u' is found within the answer.
'drug' could be 'c' (C is an example) and 'c' is found within the answer.
'from' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
The remaining letters 'lis' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'such' acts as a link.
Can you help me to learn more?
(Other definitions for coulis that I've seen before include "Thin sauce made from fruit puree" , "Thin vegetable puree" , "Fruit-puree sauce" , "Fruit pure" .)
