Get a new gold dessert (6)
I believe the answer is:
gateau
'dessert' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'get a new gold' is the wordplay.
'new' indicates an anagram.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'get'+'a'='geta'
'geta' is an anagram of 'gate'.
'gate'+'au'='GATEAU'
Can you help me to learn more?
(Other definitions for gateau that I've seen before include "Rich cream cake" , "Richly decorated cake" , "Creamy dessert cake" , "Calorie-laden cake" , "Fancy cake" .)
