Setter in dairy put cash on the counter (6)
I believe the answer is:
rennet
'setter in dairy' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'cash on the counter' is the wordplay.
'cash' becomes 'tenner' (slang for UK ten pound note).
'on the counter' says the letters should be written in reverse (counter can mean in the opposite direction).
'tenner' written backwards gives 'RENNET'.
'put' acts as a link.
Can you help me to learn more?
(Other definitions for rennet that I've seen before include "apple" , "Dairy product" , "Causing vomiting" , "substance used for curdling" , "Cheese-making curdler" .)
