Notes
This old fashioned rice pudding recipe can be stored in an airtight container and kept in the fridge for up to 4 days. You can also freeze rice pudding when stored in a freezer-safe container (for up to 3 months). Make a big batch and store rice pudding until the next time you want a sweet treat.
Keep in mind that if you use skim milk, almond milk, or any other reduced-fat milk, it will make the rice pudding runnier. You can also use evaporated milk or sweetened condensed milk, both of which can enhance the flavor.
Add additional milk if your rice pudding becomes too thick.
