Wrongly made out it's Parma beef (8)
I believe the answer is:
pastrami
'beef' is the definition.
(pastrami is a kind of beef)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pastrami that I've seen before include "Seasoned smoked beef, served in thin slices" , "smoked joint" , "beef dish" , "Thinly sliced beef" , "Sliced cured beef" .)
