Don’t forget to screenshot the ingredients list at the bottom of the guide for the next time you go in store.

  1. Combine ingredients

    Put a 1.7kg Tesco Finest smoked Wiltshire gammon joint in a large pan. Cover with 1 litre apple juice and top up with cold water to cover. Add 2 bay leaves, 6 peppercorns, 1 star anise, 1 roughly chopped carrot and stick of celery and 1 halved small onion.

    Combine ingredients
  2. Cook

    Bring to the boil, then turn down and simmer for 1 hour 30 minutes, topping up with boiling water (enough to cover), if needed.

  3. Glaze

    Preheat the oven to gas 5, 190°C, fan 170°C. To make a glaze, mix 100ml maple syrup, 1 tbsp grainy mustard, 1 tbsp soy sauce and the zest and juice of 1 clementine in a small pan. Bring to the boil, then bubble for a couple of minutes until syrupy.

  4. Prepare

    Remove the ham and allow to cool a little. Carefully remove the skin, leaving an even layer of fat. Score the fat all over in a criss-cross pattern – this allows the glaze to soak into the ham, and the fat to get extra crispy. Stud with about 16 cloves and place the ham in a small roasting tray lined with baking paper.

  5. Baste

    Spoon half the glaze over the fat and roast in the oven for 15 minutes. Then spoon over the rest, and return to the oven for a further 25 minutes. Baste the ham with the pan juices and turn the tin every so often so the fat colours evenly.

  6. Carve

    Remove from the oven and allow to rest for 5 minutes before carving.
