Spaghetti carbonara

Method Place the broad beans in a large heatproof bowl. Cover with boiling water. Set aside for 5 minutes to thaw. Rinse under cold running water. Drain. Peel and discard the skins. Cook the pasta in a large saucepan of salted boiling water until al dente. Drain. Return to the pan. Meanwhile, heat the oil in a frying pan over medium heat. Cook the bacon or pancetta, stirring occasionally, for 5 minutes or until crisp. Add the leek and garlic, and cook for 1 minute or until the leek is soft. While the pasta is cooking, combine the eggs, egg yolks, parmesan and cream in a bowl. Season with pepper. Add the broad beans, bacon mixture, egg mixture and parsley to the pasta. Toss to combine. Season with salt and pepper. Divide among serving plates and top with shaved parmesan.
