Fruit in espagnole Maxim's served up (5)
I believe the answer is:
melon
'fruit' is the definition.
(melon is a kind of fruit)
'in espagnole maxim's served up' is the wordplay.
'in' indicates the answer is hidden within the clue.
'served up' is a reversal indicator.
'nolem' can be found hidden inside 'espagnole maxims'.
'nolem' in reverse letter order is 'MELON'.
(Other definitions for melon that I've seen before include "Ogen or cantaloupe, for instance" , "Edible gourd" , "Sweet juicy fruit" , "Gourdlike fruit" , "Eg, cantaloupe, galia" .)
