Dried beef, cocoa, regularly, for girl (7)
I believe the answer is:
rebecca
'girl' is the definition.
'dried beef cocoa regularly' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'dried'+'beef'+'cocoa'='driedbeefcocoa'
The alternate letters of 'driedbeefcocoa' are 'REBECCA'.
'for' acts as a link.
(Other definitions for rebecca that I've seen before include "Maxim she betrayed" , "Literary heroine" , "She married Maxim first" , "Du Maurier novel - Hitchcock thriller" , "Isaac's wife" .)
