How to cook
Peel the potatoes. Together with the carrot boil in salted water. After boiling, they are taken out in another container, where they are strained.
Already strained, they return to the water in which they were boiled. Stir well and if the amount of water is more, let it boil until it thickens. Add the butter.
With the yogurt and the egg, a liaison is prepared, which is mixed with a ladle of the soup. Finally, add the savory. Optionally served with croutons and 1 teaspoon salted cream.
