Ingredients

• For the Meatballs:
• 1 lb (450g) lean ground veal, beef, or a mix (a 50/50 ground beef and pork blend is traditional)
• 1 large onion, finely minced
• 1 large egg
• 2 slices day-old white bread, soaked in milk and squeezed dry, or 1/2 cup breadcrumbs
• 2 tablespoons fresh parsley, chopped
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• Optional: 1 small anchovy fillet, finely minced (adds umami, not fishiness)
• For the Broth:
• 6 cups (1.5 liters) beef or vegetable broth
• 1 bay leaf
• 5-6 whole black peppercorns
• 1 small onion, quartered
• For the Creamy Caper Sauce (Lemon Caper Sauce):
• 4 tablespoons unsalted butter
• 4 tablespoons all-purpose flour
• 2 cups (480ml) reserved meatball cooking broth
• 1/2 cup (120ml) heavy cream or heavy whipping cream (or sour cream sauce for a tangier finish)
• 3-4 tablespoons capers, drained (plus a splash of brine for extra zest)
• 2 tablespoons fresh lemon juice (key for the lemon caper sauce)
• Salt and white pepper to taste
• Fresh parsley, chopped, for garnish

Directions

1. Prepare the Meatball Mixture: In a large bowl, combine the ground meat, finely minced onion, egg, squeezed bread (or breadcrumbs), chopped parsley, salt, pepper, and optional anchovy. Mix gently but thoroughly with your hands until just combined. Overmixing can lead to dense meatballs.
2. Forming Meatballs: Roll the mixture into uniform, golf-ball-sized meatballs, about 1.5-2 inches in diameter. Aim for roughly 16-20 meatballs. Place them on a plate, ensuring they have a little space between them.
3. Simmering in Broth: In a large pot or Dutch oven, bring the beef or vegetable broth with the bay leaf, peppercorns, and quartered onion to a gentle simmer over medium heat. Carefully add the meatballs to the simmering broth. Do not boil vigorously; maintain a gentle simmer (around 190-200°F / 88-93°C). Cook for 15-20 minutes, or until the meatballs are cooked through and reach an internal temperature of 160°F (71°C).
4. Straining Broth: Carefully remove the cooked meatballs from the broth with a slotted spoon and set them aside. Strain the cooking broth through a fine-mesh sieve into a clean bowl, discarding the solids. You'll need 2 cups of this flavorful broth for the sauce.
5. Making the Caper Cream Sauce: In the same pot (cleaned), melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux. This helps thicken the sauce and remove the raw flour taste. Gradually whisk in the 2 cups of reserved, strained broth until smooth and lump-free. Bring to a gentle simmer, stirring, until the sauce begins to thicken. Reduce heat to low.
6. Finishing Touches & Plating: Stir in the heavy cream (or sour cream), capers, and fresh lemon juice. Season with salt and white pepper to taste. Gently return the meatballs to the sauce and let them warm through for a few minutes. Garnish with fresh parsley before serving.
