Pacific state importing South Indian pastry (6)
I believe the answer is:
samosa
'indian pastry' is the definition.
(pastry in Indian cooking)
'pacific state importing south' is the wordplay.
'pacific state' becomes 'samoa' (country in the Pacific Ocean).
'importing' is an insertion indicator.
'south' becomes 's' (abbreviation).
'samoa' going around 's' is 'SAMOSA'.
(Other definitions for samosa that I've seen before include "Asian food" , "Savoury turnover" , "Triangular fried pastry" , "Indian fried pastry" , "Grub from India" .)
