How to make
Peel the potatoes. Along with the carrots, boil them in salted water. After boiling them, move them to another dish and mash them.
After mashing, return them to the water in which you boiled them. Mix well and if the amount of water is too much, leave to simmer until thickened. Add the butter.
From the yogurt and egg, make a thickener, mix it with a ladle of the soup. Finally, add the savory. Optionally, serve with croutons and 1 teaspoon of salty cream.
