Biscuit a somewhat naughty serving man eats (9)
I believe the answer is:
garibaldi
'biscuit' is the definition.
(I've seen this before)
'a somewhat naughty serving man eats' is the wordplay.
I cannot quite see how this works, but
'a' is within the answer.
'man' could be 'bald' and 'bald' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for garibaldi that I've seen before include "leader of nationalists" , "military commander" , "Lady's blouse" , "Biscuit with currants" , "Italian nationalist; biscuit" .)
