Bring the water to boil. Whisk your rye flour in the water while continuing to stir.
Let the porridge gently boil on low heat while stirring with a whisk regularly so it does not form clumps.
Serve the porridge warm. Leftovers can be stored in the fridge. The porridge can be enjoyed as cold also.
Notes
Ps: This porridge can be left to simmer for an hour, the taste develops somewhat deeper and sweet, but it can be eaten after 20-30 minutes of boiling. Traditionally served with butter and milk, and some sprinkled sugar on top. Ceylon cinnamon also goes well as topping. Other traditional combinations/toppings are frozen or fresh berries and berry soups. Pro tip: mix ½ cup mashed lingonberries in the rye porridge when boiling and you get even more nutrition.
