Start by rinsing the uncooked rice thoroughly under cold water. This process removes excess starch and helps prevent the rice from becoming gummy. You'll want to rinse it until the water runs clear, about two or three times. This is a vital step to achieve the desired texture.

In a medium-sized pot, combine the rinsed rice and filtered water. Bring this mix to a boil over medium heat. Once it reaches a boil, reduce the heat to low, cover, and simmer for about 15 minutes. This will allow the rice to soften and absorb the water.

After the rice has absorbed most of the water, stir in the milk, cinnamon stick, salt, and vanilla extract. Increase the heat slightly, and let it simmer gently. This step allows the flavors to meld, and you'll start to see the mixture thicken.

Once your pudding starts to thicken, it’s time to add the sugar. Use one cup to start, and adjust based on your personal preference. Stir until the sugar dissolves completely. You can always taste at this point and see if you’d like it sweeter.

Now, fold in the orange zest and raisins or dried cranberries. These ingredients add a fun pop of flavor and texture. Let everything simmer for another 5 to 10 minutes. The pudding should be thick, creamy, and divine.

You can choose to enjoy your rice pudding warm right off the stove or transfer it to a serving dish to cool in the refrigerator. If opting for the latter, let it chill for at least an hour before serving. Either way, it’s a treat that's hard to resist.
