Crossword Genius

Fruit ice with wrong coatings removed (6)

Ross

I believe the answer is:

citron

'fruit' is the definition.
(citron is a kind of fruit)

I can't explain the remainder of the clue.

(Other definitions for citron that I've seen before include "Tree producing fruit" , "Large lemon-like fruit" , "It's like a lemon" .)

I've seen this clue in The Times.
