Open to being bribed with calf meat and top notch stuffing (5)
I believe the answer is:
venal
'top notch stuffing' is the definition.
Both the answer and definition are adjectives. Perhaps you can see a link between them that I can't see?
'open to being bribed with calf meat' is the wordplay.
'open to' is an insertion indicator (some letters open up to include others).
'being bribed with' becomes 'n' (I am not sure about this - if you are sure you should believe this answer much more).
'calf meat' becomes 'veal' (I've seen this before).
'n' inserted within 'veal' is 'VENAL'.
'and' is the link.
Can you help me to learn more?
(Other definitions for venal that I've seen before include "Motivated by bribery" , "Susceptible to bribery" , "can be bought cheaply" , "Influenced by bribery, corrupt" , "Capable of being corrupted" .)
