Girl sprinkles salt over some stuffing (4)
I believe the answer is:
lass
'girl' is the definition.
(lass can informally mean a girl)
'sprinkles salt over some stuffing' is the wordplay.
'some stuffing' indicates the answer is hidden within the clue.
'over' says the letters should be written in reverse.
'ssal' is hidden within 'sprinkles salt'.
'ssal' back-to-front is 'LASS'.
(Other definitions for lass that I've seen before include "Scottish girl" , "Miss" , "Familiar form of address for female" , "Damsel" , "Young woman (-. Eng.)" .)
