Traditional Scottish dish (6)
I believe the answer is:
haggis
'traditional scottish dish' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for haggis that I've seen before include "Burns Night fare" , "Scottish dish boiled in sheep's stomach" , "Dish boiled in a skin made from an animal's stomach" , "Scotland's national dish" , "traditional meal" .)
