Billed one with some ingredients rising (5)
I believe the answer is:
eider
'billed one' is the definition.
(eiders have beaks or bills)
'with some ingredients rising' is the wordplay.
'with' says the answer is hidden in the clue.
'rising' says the letters should be written backwards (going up in a down clue).
'redie' is hidden within 'some ingredients'.
'redie' written backwards gives 'EIDER'.
(Other definitions for eider that I've seen before include "Duck from which down is obtained" , "Duck noted for down" , "Large sea duck" , "Reed I turn into a duck" , "Duck valued for its fine soft down" .)
