Lemony Parsley-And-Egg Soup

• 2 tablespoons butter
• 1 medium onion, chopped
• 4 cups parsley (about 3 bunches)
• 6 cups vegetable or chicken stock
• Salt and black pepper
• 4 eggs
• 1/3 cup freshly squeezed lemon juice
• 1/2 cup heavy cream, optional
• Sour cream for garnish, optional.

1. 1. Put the butter in a large saucepan over medium-high heat. When it melts, add the onion and cook, stirring occasionally, until softened, about 5 minutes. Add the parsley and cook, stirring occasionally, until it wilts, 3 to 5 minutes. Stir in about half the stock.
2. 2. Puree the soup in the pan with an immersion blender, or cool slightly, pour into an upright blender and puree carefully. Return to the pan with the remaining stock. Heat through over medium-low heat, then season to taste with salt and pepper.
3. 3. Beat together the eggs and lemon juice, then slowly add about 1 cup of the hot soup, whisking all the while. Gradually stir the egg mixture back into the soup. Taste and adjust the seasoning, then stir in the cream if you're using it, or serve garnished with a dollop of sour cream, if you like.
