Start cooking the lentils. Place the lentils in a small saucepan or saucepan and pour in clean cold water in a ratio of 1:2. Put on medium heat and, stirring, bring the water to a boil. As soon as the liquid boils, a lot of white foam will form on the surface - carefully remove it, then add salt and stir.
Boil the lentil porridge. Reduce heat to low and cook for 10-15 minutes, until the grains are soft and the liquid has completely evaporated. You can cover the pan with a lid or do without it at all. Keep in mind that if you close the lid tightly, the porridge will constantly boil over.
