Feature of Porterhouse that's blemish on conspicuous wealth? (8)
I believe the answer is:
marbling
'feature of porterhouse' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'blemish on conspicuous wealth?' is the wordplay.
'blemish' becomes 'mar' (I've seen this in another clue).
'on conspicuous wealth?' becomes 'bling' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'mar'+'bling'='MARBLING'
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for marbling that I've seen before include "Distribution of fat" , "Streaky lines" , "Mottled effect" .)
