    • Preparation time: 10 minutes
    • Cooking time: about 3-4 1/2 hours, plus 10-15 minutes resting
    • Total time: 3 hours 55 minutes to 4 hours 55 minutes, including resting 60 minutes 60 minutes 60 minutes 60 minutes 55 minutes

    Serves: Serves 6 (with some leftovers)


    • 3-4kg Aberdeen Angus prime rib of beef (bone in), available from the Meat Service Counter
    • 1 onion, halved
    • 1 tbsp Colman's Mustard Powder
    • 1 tbsp plain flour
    • 300g tub fresh Joubère Beef Gravy
    • 2 tbsp double cream
    • A few strands Waitrose Cooks' Ingredients Kashmiri Saffron
    • 2 x 450g packs fresh Waitrose Mashed Potato


    1. Preheat the oven to 180°C, gas mark 4. Weigh the beef to calculate the cooking time (allow 20 minutes per 500g for rare, plus 20 minutes; 25 minutes for medium, plus 25 minutes; or 30 minutes for well done, plus an extra 30 minutes). Place the rib in a large roasting tin with the halved onion. Mix together the mustard and flour and rub well into the surface of the beef. Season generously and roast for the calculated cooking time, basting regularly.
    2. Remove the beef from the oven and place on a carving board. Cover loosely with foil and rest for 10-15 minutes. Discard the onion and pour off and discard the excess fat from the tin. Place the tin over a low heat, add the gravy and mix with any meat juices. Simmer for 1-2 minutes. Strain through a sieve before serving.
    3. In a large pan, gently warm the cream then remove from the heat. Add the saffron and leave to infuse for 2-3 minutes. Heat the mash according to pack instructions. Add to the cream and beat well. Serve the beef, sliced, with baby leaf greens and a 200g pack Waitrose Red Cabbage with apple, red wine and cranberries.
