Northern Ireland: Starter and Fish

It's the 20th anniversary series of Great British Menu, and four chefs compete for Northern Ireland with canapes, starters and fish dishes celebrating great Britons of the past for a banquet at historic Blenheim Palace.The dishes are judged by Michelin-starred chef Angela Hartnett, and they include a fusion dish of ajo blanco and vine leaf dolmas, and four dishes that each use a different fish: brill, coley, cod and sea trout.
