Something cheesy coming from pantomime dame (4)
I believe the answer is:
edam
'something cheesy' is the definition.
(type of cheese)
'coming from pantomime dame' is the wordplay.
'coming from' indicates the answer is hidden within the clue.
'EDAM' is hidden in the letters of 'pantomime dame'.
(Other definitions for edam that I've seen before include "Dutch specialty" , "Madeinto popular cheese" , "Dutch market town famous for its cheese" , "Mild yellow Dutch cheese" , "Made (anag) - Dutch cheese" .)
