Dip in hole (6)
I believe the answer is:
pickle
This clue might be a double definition.
'dip in' is the first definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'hole' is the second definition.
(I know that hole can be written as pickle)
Can you help me to learn more?
(Other definitions for pickle that I've seen before include "Relish, difficult situation" , "Relish; preserve" , "A preserve or an informal predicament" , "Preserve in liquid" , "A preserved vegetable or a fine mess" .)
