SPAGHETTI ALLA CARBONARA

Steps:

• Bring a large pot of salted water to a boil. Add pasta, and cook until al dente, about 7 to 9 minutes.
• Just before the pasta is cooked, fry the pancetta in a large skillet until it is crisp and golden brown, 5 to 6 minutes. Drain the pasta well, reserving 1/4 cup of the cooking water. Carefully pour it into the skillet, then add the pasta, and heat, shaking the pan, for 1 minute. Add the grated cheese, the egg whites and pepper, and toss until they are fully incorporated.
• Divide the pasta among 4 heated serving bowls, and make a nest in the center of each. Gently drop an egg yolk into each nest, season with additional black pepper, and grate additional cheese on top. Serve immediately.
