Mary McCartney is making the perfect meal for family celebrations with the perfect guest -- her dad, the legendary musician and songwriter Sir Paul McCartney. It's a classic British Roast Dinner with a shortcut, store-bought roast and all of the McCartney family's favorite homemade sides: a vegan version of the Yorkshire Puddings that Mary's dad loves, a take on the Celebration Stuffing that Mary's mum taught her to make, a spin on Brussels sprouts in a stir-fried slaw, beautiful Rosemary Roasted Potatoes and Parsnips and lashings of must-have Red Wine Gravy. Sir Paul gives the holiday feast a taste test and shares the secret recipe to his signature cocktail, a Maccarita. There are entertaining tips and great times in this totally unique party for two with one of the greatest stars in the world and his incredible daughter.
