Beset by fake mince and cattle meat (9)
I believe the answer is:
beefsteak
'cattle meat' is the definition.
'beefsteak' can be an answer for 'meat' (beefsteak is a kind of meat). I am not sure about the 'cattle' bit.
'beset by fake mince' is the wordplay.
'by' is a charade indicator (letters next to each other).
'mince' indicates anagramming the letters.
'beset'+'fake'='besetfake'
'besetfake' anagrammed gives 'BEEFSTEAK'.
'and' is the link.
Can you help me to learn more?
(Other definitions for beefsteak that I've seen before include "something to be eaten" , "used for club" , "Porterhouse, sirloin, or T-bone, for example" , "Thick lean slice of meat for grilling or frying" , "Thick cut of meat" .)
