When rice is cooked, take lid off, turn rice cooker off. Pour in coconut milk and stir well, breaking up any lumps of rice. Add sugar and stir in. Turn on cooker, put cover on and bring to a boil. Taste and add more sugar if you wish. Leave lid off and cook stirring occasionally until most of coconut milk is absorbed. Add cashews, raisins and ground cardamom, stir. Enjoy pudding warm or cold.
