Entrance with gold dessert (6)
I believe the answer is:
gateau
'dessert' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'entrance with gold' is the wordplay.
'entrance' becomes 'gate' (type of entrance).
'with' means one lot of letters go next to another.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'gate'+'au'='GATEAU'
Can you help me to learn more?
(Other definitions for gateau that I've seen before include "Cake (from the Black Forest?)" , "named for Black Forest?" , "Cake for Pierre" , "Cream dessert cake" , "Black Forest dessert" .)
