Combine first 6 ingredients in a large saucepan and bring to a boil; stirring frequently. Transfer to a slow cooker, cover and simmer on LOW until rice is tender, about 3-4 hours. If necessary, add additional coconut milk or water; consistency should resemble creamy rice porridge. Remove from heat and cool. Whip cream to soft peaks. Before folding in the cream, ensure that rice is creamy and fluid; adding more coconut milk if necessary. Pour into serving dishes and refrigerator, until cold.
