Begin by placing the cooked rice and coconut milk in a large saucepan. Allow them to gently simmer over medium heat. Gradually introduce the full-fat coconut milk, honey, ground cardamom, and a pinch of salt. Stir the mixture consistently until it thickens, which should take approximately 8-10 minutes.

Once the pudding base has achieved a desirable thickness, stir in the raisins, pistachios, shredded coconut, and the zest of one orange. Remove the pan from heat, letting the flavors meld as the pudding cools slightly. The mixture will continue to thicken during this cooling period.

Scoop the creamy concoction into individual serving dishes. Serve immediately to relish the warm, comforting flavors, or refrigerate until ready to serve for a chilled sweet treat.
