Side dish found in Christmas hampers (4)
I believe the answer is:
mash
'side dish' is the definition.
'mash' can be an answer for 'dish' (I have seen 'dish of veg' mean 'mash' so perhaps 'dish' could also mean 'mash'). I am unsure of the 'side' bit.
'in christmas hampers' is the wordplay.
'in' says the answer is hidden in the clue.
'MASH' is hidden within 'christmas hampers'.
'found' acts as a link.
Can you help me to learn more?
(Other definitions for mash that I've seen before include "Pureed potato" , "Black comedy film set in Korean War" , "Pulped potatoes" , "Forces hospital" , "Pured potato" .)
