Pavese Soup

Preheat the oven to moderate temperature (170°F)

Spread a generous amount of butter on one side of the bread slices

Place them, with the buttered side up, in a baking dish and let them toast and crisp for 15-20 minutes or until golden brown

Sprinkle each slice with 1 tablespoon of grated Parmesan cheese and let it melt slightly

Bring the broth to a boil, then reduce the heat and let it simmer

Pour the hot broth into 4 bowls or soup plates, heated

In each bowl, place 1 bread slice and let it rest for 2-3 minutes

Then, carefully place 1 raw egg yolk on top of each bread slice, and if desired, sprinkle more grated Parmesan cheese

Serve four portions.
