Russian ballerina (7)
I believe the answer is:
pavlova
'russian ballerina' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pavlova that I've seen before include "Sweet - dancer" , "course" , "Ballerina - cake" , "Meringue dish" , "Surname of ballerina" .)
