Dessert choice (3)
I believe the answer is:
pie
'dessert choice' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pie that I've seen before include "In the sky, it's a hopeless idea" , "something with custard, say" , "Fruit or meat dish" , "Crusty dish" , "Dish baked in pastry-lined pan" .)
