Whisky glass emptied over, say, picnic food (6,4)
I believe the answer is:
scotch eggs
'whisky glass emptied over say picnic food' is the definition.
I can't judge whether this defines the answer.
'whisky glass emptied over say' is the wordplay.
'whisky' becomes 'scotch' (Scotch whisky is an example).
'emptied' suggests removing the centre.
'over' indicates putting letters inside.
'say' becomes 'eg'.
'glass' with its middle taken out is 'gs'.
'scotch'+'gs'='scotchgs'
'scotchgs' enclosing 'eg' is 'SCOTCH EGGS'.
Can you help me to learn more?
(Other definitions for scotch eggs that I've seen before include "Items of food" , "Sausage-meat savouries" , "Snacks" .)
