Hide dough in ear (5)
I believe the answer is:
cache
'hide' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for cache that I've seen before include "Treasury" , "Hidden store of things" , "Concealed store" , "Collection of hidden things" , "Conceal" .)
