Small dish containing large plug (5)

I believe the answer is:

spile

'plug' is the definition.
(spile is a kind of plug)

'small dish containing large' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'dish' becomes 'pie' (I've seen this before).
'containing' indicates putting letters inside.
'large' becomes 'l'.
'pie' placed around 'l' is 'pile'.
's'+'pile'='SPILE'

(Another definition for spile that I've seen is " plug".)

I've seen this clue in The Independent.
