Fry the cereal. Pour the cereal into a dry, hot frying pan. Stir for 7-10 minutes. When all the grains are evenly fried and acquire a bronze hue, the cereal is ready for cooking.
Cook the porridge. Salt the water in a saucepan and put it on the fire. When the water boils, stir to dissolve the salt. Pour the fried cereal into the boiling water. Reduce the heat, cover with a lid, and cook for 20 minutes. Stir the porridge occasionally to prevent it from burning. When all the liquid has evaporated, the porridge is ready.
Season the porridge. Divide the barley porridge into bowls, add 10 g of butter to each serving.
