Like shoulders of beef or lamb, they can be smoked (6)
I believe the answer is:
joints
This clue is a double definition.
'like shoulders of beef or lamb' is the first definition.
(beef and lamb shoulders are joints)
'they can be smoked' is the second definition.
(as in cannabis)
(Other definitions for joints that I've seen before include "Junctions, unions" , "Structures in body in which bones are fitted together" , "Points of connection between two elements" , "Points of connection between two bones" .)
