Resort to cornmeal crackers (5,5)
I believe the answer is:
monte carlo
'resort' is the definition.
(holiday resort in Monaco)
'to cornmeal crackers' is the wordplay.
'crackers' indicates an anagram (informal term for mad).
'to'+'cornmeal'='tocornmeal'
'tocornmeal' anagrammed gives 'MONTE CARLO'.
(Other definitions for monte carlo that I've seen before include "Destination of a car rally - place with a famous casino" , "Riviera resort" , "Gambling resort in Monaco" , "Gamblers' resort" , "Swanky part of France" .)
