Shellbows pasta, also known as lumache, is a shell-elbow hybrid and is as fun to say as it is to eat. Thicker, creamier sauces are easily captured in its curved tube and ridged exterior, making it a superstar cut for dreamy baked pasta dishes. DeLallo Shellbows Pasta is made with an exclusive blend of the highest quality durum wheat with a high gluten content. It cooks up for that signature al dente texture.
