Peel, core and chop the apples. Pit the dates and quarter them lengthwise. Put both the chopped apples and dates along with the orange juice, salt, cinnamon stick and star anise in a pan and bring it to boil. Turn down the heat, and simmer until the fruit is cooked and tender but not mushy.
Discard the cinnamon stick and star anise and divide the fruit equally between four oven-proof dishes.
In a small bowl, mix together the ingredients for the crumble and sprinkle over the fruit. Bake the dates and apple crumble at 180C (350C) for 8 to 10 minutes.
Serve with cream or vanilla ice-cream.
