Pasty (3)
I believe the answer is:
pie
'pasty' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for pie that I've seen before include "Bird - dish - mixed type" , "Slapstick missile" , "In the sky, this dish is impractical" , "Dish baked in pastry-lined pan" , "Confused, mixed type" .)
