The good you can get from a beef tin (7)
I believe the answer is:
benefit
'the good' is the definition.
(benefit is a kind of good)
'from a beef tin' is the wordplay.
'from' indicates an anagram (the anagram comes from the same letters).
'beef'+'tin'='beeftin'
'beeftin' with letters rearranged gives 'BENEFIT'.
'you can get' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for benefit that I've seen before include "Advantage or blessing" , "Advantage (from social security?)" , "Something that aids" , "Good" , "Payment" .)
