Mary McCartney is remixing the classics with her own spin and uncovering the secrets of her friend and Foo Fighters frontman Dave Grohl's Badass Lasagna. She cooks up Smokey Dogs with all the fixings, a fabulous Chef's Salad inspired by her mom and an incredible Banoffee "Cheese"Cake. Then it's over to Los Angeles for Dave's self-shot recipe video directed by his young daughter and a transatlantic taste-off as Dave and Mary check out each other's eats.
