Summer Meatballs

Preparation

1. Step 1

   To prepare sauce: in bowl of a food processor, combine onion, garlic, celery, carrot and lemon zest. Process until minced. Place large saucepan or flameproof casserole over medium-low heat, and add oil and butter. Add minced vegetables and salt to taste. Sauté gently until softened but not browned, about 10 minutes.

2. Step 2

   Add sugar, passata and 2 cups water. Cover, and simmer 15 minutes. Add milk, and cook, uncovered, 15 minutes more. Meanwhile, begin preparing meatballs.

3. Step 3

   To prepare meatballs: in a large bowl, combine ground turkey, ground pork, bread crumbs, garlic and egg; mix well. Add pecorino, basil, and salt and pepper to taste. Mix until thoroughly blended.

4. Step 4

   Line a large baking sheet with plastic wrap. Dampen hands with cold water, and roll rounded teaspoonfuls of meatball mixture, placing meatballs on sheet; there should be about 80. Add meatballs to simmering sauce, shaking pan gently to make room as they are dropped in; do not stir. Simmer, partly covered, until meat is cooked through, 20 to 25 minutes.

5. Step 5

   To serve, transfer meatballs and sauce to a serving bowl, and sprinkle with pine nuts and whole basil leaves. Serve, if desired, with cooked rice, garnishing each serving with more pine nuts and chopped basil.
