Grab pastries, soft in the middle — a Scottish speciality (8)
I believe the answer is:
bagpipes
'the middle a scottish speciality' is the definition.
I can't judge whether this defines the answer.
'grab pastries soft in' is the wordplay.
'grab' becomes 'bag' (I can't justify this - if you can you should believe this answer much more).
'pastries' becomes 'pies' (pie is a kind of pastry).
'soft' becomes 'p' (musical abbreviation for piano, 'soft').
'in' is an insertion indicator.
'pies' going around 'p' is 'pipes'.
'bag'+'pipes'='BAGPIPES'
Can you help me to learn more?
(Other definitions for bagpipes that I've seen before include "Scottish wind instruments" , "Scottish wind instrument" , "can be heard in the highlands" , "Wind instrument with a chanter" , "Scots musical instrument" .)
