A recipe from grandmother's more thrifty times; rarely encountered
Melt the butter, and whisk in flour. Add meat broth or water. Add the
rinsed and chopped herbs, and briefly bring to a boil. Let soup cool
a bit, then thicken with egg yolk. Season with salt, pepper, and a
pinch of sugar. Stir in sour cream when serving.
In some Swabian kitchens, very finely chopped garlic gets scattered
on top of the soup.
