Hostess's porridge is hardly dipped into (6)
I believe the answer is:
geisha
'hostess's' is the definition.
(Japanese woman hosting or entertaining men)
'porridge is hardly dipped into' is the wordplay.
'dipped into' indicates the answer is hidden within the clue (the answer has been dipped into the clue).
'GEISHA' can be found hidden inside 'porridge is hardly'.
(Other definitions for geisha that I've seen before include "Japanese serving girl" , "Female escort" , "Professional female companion for Japanese men" , "He's a GI (anag.)" , "Hostess in a kimono" .)
