Head for the cake (7)
I believe the answer is:
crumpet
I believe this is a double definition.
'head' is the first definition.
(thesaurus)
'cake' is the second definition.
(I've seen this before)
'for the' is the link.
(Other definitions for crumpet that I've seen before include "Breakfast" , "Tea cake" , "Round yeast cake eaten hot with butter" , "Muffin" , "Something eaten toasted and buttered" .)
