Throws company function, finding a dish from the north (9)
I believe the answer is:
lobscouse
'a dish from the north' is the definition.
(northern English dish)
'throws company function' is the wordplay.
'throws' becomes 'lobs' (lobbing is a kind of throwing).
'company' becomes 'co' (abbreviation).
'function' becomes 'use' ('use' can be a synonym of 'function'**).
'lobs'+'co'+'use'='LOBSCOUSE'
'finding' is the link.
(Other definitions for lobscouse that I've seen before include "sailor's dish" , "Stew associated with Liverpudlians" .)
