In a large bowl, combine the chicken, the ham (if using), the corn, the pineapple, the apple, the raisins, the walnuts, the table cream and the mayo and mix well. Taste to check seasoning and add salt if necessary.

Bring the bowl to the fridge and let it sit overnight.

The next day, transfer to a serving dish and sprinkle the potato sticks on top. Add some chopped parsley and some more walnuts and raisins to decorate, if you want.

Serve cold or at room temperature.
