Penne are tube- shaped with angled ends cut to resemble a quill or pen point. They have ridges which allow them to hold more sauce. Ridged penne are designed for meat, vegetable, cheese and oil or butter-based sauces. They are also perfect for baked dishes made with sauce and cheese. Penne all’Arrabbiata, penne with a spicy tomato sauce, is a favorite Italian dish.
