Cutting pastry (4)

I believe the answer is:

tart

I believe this is a double definition.

'cutting' is the first definition.
(I've seen this before)

'pastry' is the second definition.
(tart is a kind of pastry)

(Other definitions for tart that I've seen before include "quiche, perhaps" , "The pastry sounds bitter" , "Professional woman" , "loose woman" , "Acid-tasting; pastry" .)

I've seen this clue in The Times.
