This is me at college, before being covered in flour etc (8)
I believe the answer is:
meuniere
'flour etc' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'this is me at college before being covered in' is the wordplay.
'this is me' becomes 'me'.
'at college' becomes 'uni' (I can't explain this - if you can you should believe this answer much more).
'before' becomes 'ere' (poetic term).
'being covered in' is a charade indicator (letters next to each other) (some letters go on top of or cover others).
'me'+'uni'+'ere'='MEUNIERE'
Can you help me to learn more?
(Other definitions for meuniere that I've seen before include "Style of cooking" , "how fish could be" .)
