  • 2 litres of cola/coke (not diet) (£0.70)
  • 1 tsp garlic granules
  • 1 tsp ground cinnamon

Metric - US Standard

Instructions

  • Start by adding your gammon joint to your slow cooker. Add the onion, carrots, cola/coke, garlic granules and ground cinnamon. Gently stir to combine and cover with the lid. Slow cook for 6 to 7 hours on low or 4 to 5 hours on high.
  • After this time, use two spatulas to remove the ham from your slow cooker and place on a foil lined baking tray.

Preheat your oven to 180°C FAN/ 200°C conventional/350°F

  • Combine the ingredients for the glaze with a fork x whisk. Discard the string wrapped around the ham and remove the outside layer (rind) from the ham, leaving a layer of fat over the ham.
  • Score the fat with a knife, then coat the ham evenly with half of the glaze, using an oil brush or your hands. To prevent the sides from drying out, lift the foil to cover the sides of the ham, leaving the fat exposed.
  • Pop in the oven for 20 minutes, then remove and coat with another final layer of the glaze. Add back in the oven for another 20 minutes.
  • Remove from the oven and leave to rest for 20 minutes before carving or adding into the fridge to serve cold.

Notes

  • Choose a high-quality gammon joint with ample fat for flavour and juiciness.
  • Adjust the amount of liquid in the slow cooker for desired moisture; when using Cola or juices.
  • Use a meat thermometer to ensure the gammon reaches an internal temperature of 75°C/160°F to avoid overcooking.
