COLIN COWIE/ Gratin of Linguine. Gratins are beautiful, rich dishes that are filled with warmth and comfort. It pairs wonderfully with a steak, which Ming shows with his Gratin Dauphinois with Grilled Flat Iron Steak; or as its own dish like Colin Cowie's Gratin of Linguine. Long time friends, Ming and Colin show you how to customize this classic dish to your liking, making it as healthy or homey as you like, but always melt in your mouth delicious.
