Following the directions on the package, cook 2 cups of white rice.
In a sturdy saucepan, combine the warm, cooked rice, milk, 2 split-open vanilla beans, and salt.
Bring mixture to a boil over medium-high heat, stirring as it heats.
Reduce heat to a gentle simmer.
Stir occasionally, checking that the pudding cooks at no more than a gentle simmer (to prevent burning).
Cook 50 to 60 minutes.
Remove from heat and remove the vanilla beans.
The rice pudding can be eaten when still warm or when chilled in the refrigerator.
Stir in sugar to your taste.
