Gentleman left ring burning for some meat (7)
I believe the answer is:
sirloin
'some meat' is the definition.
(sirloin is a kind of meat)
'gentleman left ring burning' is the wordplay.
'gentleman' becomes 'sir' (a man may be addressed as sir).
'left ring burning' becomes 'loin' (I can't justify this - if you can you should give a lot more credence to this answer).
'sir'+'loin'='SIRLOIN'
'for' is the link.
Can you help me to learn more?
(Other definitions for sirloin that I've seen before include "Good cut of beef" , "(Knighted?) cut of meat" , "Type of steak" , "Quality cut of beef loin" , "Upper part of loin of beef" .)
