Some pancake, perchance, served up? (5)
I believe the answer is:
crepe
'some pancake perchance served up?' is the definition.
I can't tell whether this definition defines the answer.
'some pancake perchance served up?' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'served up?' is a reversal indicator (I've seen 'serves up' mean this).
'eperc' is hidden in the letters of 'pancake perchance'.
'eperc' written backwards gives 'CREPE'.
(Other definitions for crepe that I've seen before include "Light fabric; pancake" , "French dish" , "Material - French pancake" , "sole?" , "Soft thin fabric with a crinkled surface" .)
