For US home cooking, always buy penne rigate. The ridges matter.
The tube + diagonal cut + ridge combination catches sauces aggressively. Best pairings:
Penne does not pair well with:
The Roman dish: penne + tomato + garlic + chili + olive oil + Pecorino. Arrabbiata means "angry" — for the chili heat. It's the simplest possible spicy tomato pasta and a benchmark for restaurant skill.

A Roman invention from the 1980s — penne + tomato + heavy cream + vodka + Parmigiano. The vodka cooks off the alcohol but releases tomato compounds that water can't. The result is rich, pink-orange, slightly sweet with deep tomato flavor.
It's the American Italian dish that's also genuinely Italian.
Penne is neutral-wheat, sturdy, chewy. The tube format makes it a sauce-vehicle more than a pasta-flavor experience.
