Puts an end to including heads of grilled grouse in bar snacks (6,4)
I believe the answer is:
scotch eggs
'bar snacks' is the definition.
'scotch eggs' can be an answer for 'snacks' (I've seen this before). I'm not sure about the 'bar' bit.
'puts an end to including heads of grilled grouse' is the wordplay.
'puts an end to' becomes 'scotches' (I've seen this in another clue).
'including' is an insertion indicator.
'heads of' indicates taking the first letters.
The first letters of 'grilled grouse' is 'gg'.
'scotches' going around 'gg' is 'SCOTCH EGGS'.
'in' is the link.
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" .)
