Conclusion of scandal associated with gold sweet (6)
I believe the answer is:
gateau
'sweet' is the definition.
(type of dessert or sweet)
'conclusion of scandal associated with gold' is the wordplay.
I cannot really understand how this works, but
'scandal' could be 'gate' (as in Watergate and other formations) and 'gate' is located in the answer.
'gold' could be 'au' (Au is the chemical symbol for gold) and 'au' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for gateau that I've seen before include "rich food" , "Cake (from the Black Forest?)" , "Rich dessert cake" , "Black Forest dessert" , "Cake for Pierre" .)
