Pour the rice, salt and water into the pan, bring to a boil and let it cook for 3-4 minutes.
Now pour in the milk and bring it to a boil again while stirring.
Let it all boil while stirring regularly for approx. 45 minutes on even heat until the porridge has reached the right thickness.
Serve with cinnamon sugar - calculate 1 tbsp. sugar to 1 tsp. cinnamon - and a dollop of butter.
If you want to make your rice porridge under the duvet, it is between step 2 and 3 you put it to bed. Place the lid on the pan and place it in the middle of the bed on a thick, woolen blanket. Wrap the blanket around the pot and then the duvet, and leave it for 1-2 hours and never more than 3 hours as you then risk the temperature falling and the porridge becoming bad.
