Cook all the herbs in 2 tablespoons butter for 2-3 minutes.
Sprinkle with flour, then stir and cook another 4 minutes. Set aside.
Pour 6 cups of water into a pot and bring to a slow simmer. Add
salt and pepper.
Mix egg yolks, sour cream and remaining butter; whip into the
simmering soup. Cook soup over low heat, stirring, until it thickens.
Add herbs and simmer another few minutes.
Place half of a toasted roll in a soup plate and ladle soup over it.
Notes: This recipe comes from Gyula Vasvary, master chef in the
1820's of Hungary.
