In theatre he attempts to produce some warmed-up fare (6)
I believe the answer is:
reheat
'in theatre he attempts to produce some warmed-up fare' is the definition.
The definition suggests a singular noun which matches the answer.
'in theatre he attempts to' is the wordplay.
'in' says the answer is hidden in the clue.
'REHEAT' is hidden within 'theatre he attempts to'.
Can you help me to learn more?
(Other definitions for reheat that I've seen before include "Cook again" , "Jet engine afterburner" , "Warm (food) up again" , "Of cooked food, give another go in the microwave" , "Method of getting extra power from jet engine" .)
