Place the gammon in the slow cooker, pour the apple juice in the bottom, replace the lid, and cook on low for 8-10 hours, or on high for 5-6 hours.
2 kg approx joint of unsmoked gammon (ham), 300 ml clear apple juice
About half an hour from the end, preheat your oven to 200℃ / 390℉.
When the cooking time has passed, carefully use two forks to remove the gammon from the slow cooker and place it in a baking tray. If the gammon has string on it, remove it now.
Pat dry the fat on top of the gammon using kitchen roll, then score it in a diamond pattern using a sharp knife.
Pour the maple syrup on top of the gammon.
50 ml amber pure maple syrup
Place the gammon on the baking tray in the oven and cook for half an hour, until golden. Baste occasionally with the cooking juices and maple syrup during cooking.
Remove from the oven, leave to rest for at least ten minutes (if you try to cut it straightaway it may shred rather than carve as it is so soft), and then carve.
