Majeiritsa (Easter Lamb Soup)

2 tablespoons olive oil
2 onions, finely chopped, or 6 to 7 green onions, finely chopped
8 cups chicken broth
1 pound boneless lamb, trimmed of excess fat and cut
    into 1/4- to 1/2-inch pieces
1 1/2 cups chopped fresh Italian parsley
1/2 cup chopped fresh dill
1/3 cup long-grain rice
4 large egg yolks, at room temperature
1/2 cup fresh lemon juice (about 2 lemons)
Salt and freshly ground pepper to taste

In a large stockpot over medium heat, add the olive oil. Sauté onions until soft, about 5 minutes. Add chicken broth, lamb, parsley and dill. Bring to a boil, reduce heat, cover and simmer for about 1 hour.

Add rice and continue simmering until soft, about 20 minutes.

In a medium bowl, beat the egg yolks and lemon juice until frothy. Gradually add 1 to 2 cups of hot soup to egg mixture, beating vigorously with a whisk to keep eggs from curdling. Pour the egg mixture back into the pot, stirring well. Simmer for 1 minute; do not boil. Season with salt and freshly ground pepper.
