Since I eat a lot of vegetarian sauces this shape is perfect. Technically this particular shape is called penne rigate because it has ridges. The tubes will accumulate sauce and pieces of vegetables, and the ridges on this shape also hold lighter particles of spices such as fresh basil as well as sauce. This allows you to prepare a pasta that is not drowning in a sea of sauce, but not dry either.
Although I make vegetable-based sauces, the shapes are equally perfect for meat sauces. They also are very sturdy, making them a good choice for pasta dishes with heavier sauces that are laden with larger pieces of meat or vegetables.
To best illustrate how well this shape works with sauces I have uploaded a photo in the customer-supplied images at the top of this page. You can clearly see from the photo how beautifully the sauce coats and clings to the pasta, and also how easy it is to make a quick dinner since I also provided an ingredient list.
