Peach ___ (dessert) (5)
I believe the answer is:
melba
'peach dessert' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for melba that I've seen before include "Dame Nellie --, Australian soprano" , "Sort of toast" , "Dame Nellie had an ice-cream dish named after her" , "Dame Nellie --; peach --" , "Australian operatic soprano, d. 1931" .)
