  • 2 kg smoked gammon joint
  • 1.5 litres apple juice

Gammon glaze

  • 3 tbsp black treacle
  • 2 tbsp sugar
  • 1 tbsp dijon mustard


  1. Rinse your gammon carefully under the tap trying not to splash the whole kitchen! Put in your slow cooker and cover with apple juice. Cover as much of the gammon as you can with the apple juice. Put your slow cooker on high and cook for 4-6 hours or low for 6-8 hours.

  2. Put on a large plate and using a sharp knife cut off the skin and a little fat, leaving at least 2 cm of fat behind if possible.

  3. Using the knife score diagonal lines on the fat one way about 2 cm apart and then repeat going the other way. This will leave you with a diamond pattern. Mix the glaze ingredients together. Preheat your grill.

  4. Brush the glaze thickly all over the scored fat. Put under the grill so that the top is about 2 "/5 cm below the grill. Grill for about 10 minutes. The top will be burnished and black in places.

  5. You can achieve the same results by roasting in a 220 C/425 F/Gas Mark 7 oven for 15/20 minutes. Allow the Gammon to rest for 15 minutes before serving.

  6. Apply to Harley Street Face.

Recipe Notes

  • Use a meat thermometer to check when the meat reaches 71 C
  • For a smaller joint simply reduce the cooking time. Use your meat thermometer to help you know when it's ready.
  • You can use coke/cider/ginger ale or likewise to flavour the gammon
  • You can just cook it without any liquid at all. It will still be moist.
  • If cooked for 8 hours then you can make it the day before, refrigerate overnight covered and slice the next day to prevent crumbling and get beautiful slices. You can reheat then in the slow cooker until piping hot or serve it cold.
  • You can use the cooking liquid to flavour pasta, soups and stews.
  • Use a marmalade as a short cut glaze.
  • Use left overs for salads, sandwiches, quiches or pasta dishes. Ham, egg and chips takes some beating!
