In a saucepan, combine the water, your chosen unsweetened milk, and a pinch of salt.
Bring the mixture to a boil over medium heat.
Gradually add the oats, while whisking continuously to prevent clumps. Continue whisking until the porridge start to thicken.
Once the porridge starts to thicken, reduce the heat to low and keep whisking to maintain a smooth texture.
Stir in the vanilla extract, cinnamon, and nutmeg.
Let the porridge cook for another 1-2 minutes to allow the flavors to blend.
Sweeten to taste with sweetened condensed milk, or use sugar or your preferred sweetener as a substitute.
Pour the porridge into bowls and serve warm
