Dish with terrible reek over the border (8)
I believe the answer is:
kedgeree
'dish' is the definition.
(I know that Kedgeree is a type of dish)
'terrible reek over the border' is the wordplay.
'terrible' is an anagram indicator.
'over' indicates putting letters inside.
'the border' becomes 'edge' ('edge' can be a synonym of 'border').
'reek' is an anagram of 'kree'.
'kree' going around 'edge' is 'KEDGEREE'.
'with' is the link.
(Other definitions for kedgeree that I've seen before include "Rice, fish and egg dish" , "something to eat" , "Indian cookery" , "fishy meal" , "Indian rice dish" .)
