Crown of the head (4)
I believe the answer is:
pate
'crown of the head' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for pate that I've seen before include "Head - cook may make it" , "Head, perhaps bald" , "Tape for a head" , "loaf" , "Tasty meat paste, maybe de foie gras" .)
