In the late 19th century, several innovations in pasta-making technology were made. These included the creation of revolutionary metal dies and improved drying methods, which led to the development of many new shapes of pasta. However, pasta makers didn’t stop creating new and exciting shapes when the turn of the century came and went. It is thought that radiatori were created between World War I and World War II. The uniquely shaped pasta pieces closely resembled the heating fixtures known as radiators, hence their name. Home cooks soon found that the shape of radiatori was ideal for gripping sauce and added a unique, satisfying texture to many dishes, so the pasta caught on among consumers despite its unconventional appearance. Today, radiatori are produced by several brands, including Colavita, Good & Gather, and more, and are used to add “bite” and whimsy to a variety of beloved pasta dishes.
