Make loud demand for rum mixed with cola (7)
I believe the answer is:
clamour
'make loud demand' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'rum mixed with cola' is the wordplay.
'mixed with' is an anagram indicator.
'rum' anagrammed with 'cola' gives 'CLAMOUR'.
'for' is the link.
Can you help me to learn more?
(Other definitions for clamour that I've seen before include "row" , "Loud confused noise" , "Loud and persistent outcry" , "Uproar" , "Complaints" .)
