Penne Alla Vodka is a popular Italian-American pasta dish made with penne pasta, a cylindrical shape that holds sauce well. The dish features a creamy tomato sauce that includes vodka, which enhances the flavors and adds a unique depth. Typically, the sauce is made by sautéing garlic and onions in olive oil, then adding crushed tomatoes and cream. The vodka is added to the sauce to help release flavors from the tomatoes and create a smooth texture. It's often garnished with Parmesan cheese and fresh herbs, making it a comforting and flavorful meal.
