With credit blown, biscuits and gravy (6)
I believe the answer is:
ackers
'gravy' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's an association between them I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for ackers that I've seen before include "bread" , "Money (slang)" .)
