Start by rinsing the arborio rice under cold water.

In a medium saucepan, combine the rinsed rice, whole milk, sugar, salt, and vanilla extract.

Heat the mixture over medium heat until it reaches a gentle boil.

Once boiling, reduce the heat to low and let it simmer for about 20-25 minutes.

Stir the pudding every few minutes during cooking.

After 25 minutes, check if the rice is tender and the pudding has thickened.

If using, stir in the ground cinnamon.

Remove from heat and let it cool slightly before serving.

You can enjoy it warm or refrigerate it for a chilled dessert.
