Sour Egg Soup

Sour egg soup is a traditional Hungarian dish and it's easy to cook. Here is the recipe:

2 tablespoons oil
1 onion, finely chopped
2 tablespoons flour
1 teaspoon paprika
1 bayleaf
1 teaspoon salt
1/2 teaspoon pepper
5 cups water
4 eggs
2 tablespoons sour cream
vinegar

Heat the oil, onion and flour to make a roux.
When the roux is ready, remove from the heat.
Add the paprika and pour in the water.
Add the bay leaf, salt and pepper.
Boil over medium heat for about 5 minutes, until the onions are tender.
Beat two eggs and pour into the soup.
Stir constantly.
Crack the remaining two eggs one by one.
Gently pour into the soup while it is simmering.
Let them cook for about 3 minutes.
Once the eggs are done, turn off the heat.
In a small bowl mix the sour cream and some of the soup until well combined.
Stir the mixture into the soup.
Add a little bit of vinegar.
