Scarcity, wanting ideal sandwiches, cake (5,6)
I believe the answer is:
black forest
'cake' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
'scarcity wanting ideal sandwiches' is the wordplay.
'scarcity' becomes 'lack' (I've seen this in another clue).
'wanting' becomes 'for' (I've seen this in other clues).
'ideal' becomes 'best' (similar in meaning).
'sandwiches' is an insertion indicator (to sandwich is to block something in).
'lack'+'for'='lackfor'
'lackfor' going within 'best' is 'BLACK FOREST'.
Can you help me to learn more?
(Other definitions for black forest that I've seen before include "somewhere in Germany" , "Gateaux associated with this region" .)
