Paccheri Pasta from Rustichella d'Abruzzo
I've tried them all, both in the US and on many trips to Italy, and Rustichella d'Abruzzo is the one I have come to rely on. Many other brands, such as De Cecco, were decent at one time, but the quality has dramatically suffered in recent years. Rustichella d'Abruzzo, however, has remained consistent. Expensive? Yes. But considering I get two meals out of a bag (500g vs. other brands 454g), it's pennies on the table. Well worth it!
