Places one might see some sauce or hand in knickers (8)
I believe the answer is:
pantries
'places one might see some sauce' is the definition.
I can't tell whether this definition defines the answer.
'hand in knickers' is the wordplay.
'hand' becomes 'R' (abbreviation for right, as in the right-hand side).
'in' means one lot of letters goes inside another.
'knickers' becomes 'panties' (panties can informally mean knickers).
'r' put within 'panties' is 'PANTRIES'.
'or' is the link.
Can you help me to learn more?
(Another definition for pantries that I've seen is " Larders".)
