The first female british chef to win 3 Michelin stars at her own restaurant hails from a farm in County Antrim. Mark Coles talks to those who know Clare Smyth well - at home and in the kitchen - including legendary chefs Alain Ducasse and Angela Hartnett. Clare Smyth left Northern Ireland to train in England at just 16 and has gone her own way ever since. A protegee of some of the world's best known chefs, she ran Gordon Ramsay's flagship restaurant before setting up her own, Core, just three years ago. She says she's now reached the pinnacle of any chef's career - but food critic Jay Rayner questions why this milestone has been so long coming.
