Remove food from the refrigerator. Wash the rice and greens. To prepare the soup, use an enamel pan and a wooden spoon to prevent the dovga from curdling.
Pour water into a saucepan, add rice and put on fire. At this time, finely chop the greens. In a separate container, whisk the kefir a little to break up the lumps. Mix eggs with flour and add kefir. Stir.
When the rice is ready, add the greens to the pan and cook for 1-2 minutes. Then pour the kefir-egg mixture into the soup, stirring all the time so that the kefir does not curdle. Continuing to stir, bring the soup to a boil and cook for another 5 minutes; at this stage the soup does not need to be stirred. Finally add dried mint and let cool. Add salt before serving.
Salt the cold dovga and pour into plates, garnish with a sprig of mint and serve with whole grain bread.
